Let's start with the list in image #1 just because it is the most extensive and will likely address many of the others.
First on the list of image #1 is "Written down 5000 years ago." This means it was written around 3000 BC. This is about 500 years before the Great Pyramids were being built. We know that by this time most of Egyptian mythology, the core anyway, was already strongly in place. From items like the Narmer palette(Discussions of the glyphs and meaning of the palette here.) and other sources contemporary to the palatte, we also know hieroglyphs were in use before 3000 BC. Likely this date of 5000 years ago is probably wrong. On the other side of it dates for the Bible range widely as to when it was written, much of it depends on which version of the Bible one uses. What I take away from all of this is that pointing out dates for either of these documents is probably not legitimate.
We then move on to Horus being born of a virgin. This is going to get into some weird things about Egyptian mythology. As the myth goes, either Osiris impregnates Isis or after Osiris is dead and chopped up Isis uses his dismembered phallus to impregnate herself. In the most traditional sense of virgin, a woman who has never been vaginally penetrated, Isis does not fit the bill. The other common definition of virgin is unmarried. As Osiris was about to ascend to the throne he would have been married by Egyptian customs and there are references to Isis as his wife prior to the dismemberment incident. Isis is not an unmarried woman. In still other myths Isis and Osiris mingle breaths, doesn't that sound like a euphemism, when he is resurrected and that is how she becomes pregnant with Horus. It is highly unlikely that Isis is a virgin in any myths.
Horus was born on Christmas Day. Since Osiris is murdered in early October/November it is highly unlikely that Horus would have been born the next month. The main festival of Horus, which is often associated with the birth of the god or goddess, is in June/July. If we consider the Egyptian ideals of realism their mythology we can see that July as more reasonable as this is 9 months after the murder. Another fact that points to the idea that this is reasonable is that Horus is hidden in a papyrus marsh after his birth so Set would not find him. December is the middle of the Nile flood and most papyrus beds would be underwater at this time making it impossible to hide a child there. July however is the time of low water and planting which would leave much of these areas open.
I don't even know where to start with this concept of three wise men and the Eastern Star. The Eastern Star is usually thought of as Sirius, which in Ancient Egyptian mythology was a goddess, Sothis/Sopdt. (Sothis was a goddess that sometimes heralded the arrival of epidemics and plague as well as her more benign association with the Nile flood bringing fertile soils.!) I don't have much to say about the three wise men. I can't say I have ever read anything about three wise men in any Egyptian myth.
This whole line "Taken to Egypt to avoid the wrath of Typhoon" is problematic. Horus was born in Egypt, usually somewhere in the delta region in most myths. He could not have been taken to some place he already was. (Very curious) Typhoon also causes problems since this is a Greco-Roman god who is a titan offspring of Gaia. I am sure they meant Set but in calling him Typhoon this no longer refers to Egyptian myth but a later Roman idea.
Taught in the temple as a child is also not likely to be true to the myths. There are many myths of Horus' childhood. Many of them include his haphazard childhood of being hunted by Set and stung/bitten by animals. We also must consider that in the ancient world most male children of a king would have been educated, likely in a temple, regardless of their nationality. This is hardly something that would set Horus apart from most other deities or king's children.
Anup is not an Egyptian god. I assume we are dealing with a misspelling of Anpu, the Egyptian name of Anubis. (Anubis is a Greek word) Misspelling a deity name does not instill confidence in me. Baptism is not an Egyptian practice. Baptism is a Christian concept and related to the Jewish concept Tvilah to restore purity. (You can also think of this as the removal of sin.) What they are doing in this piece is blurring all of these different concepts by compiling them under the Greek word "baptismos". This Greek word refers to Jewish ritual washing. From there they are saying that because the Egyptian priests also washed before entering a temple that they were practicing "baptismos" too. This is quite a long string of things to make this comparison work. As for the rest, I can't remember any listing of an Egyptian god or goddess' age being given in years, especially specific years. Usual descriptions refer to body, so something like the body of a young boy or bent with age or they just default to millions of years.
Egyptians combined gods and goddesses into Triads. This makes the 12 disciples rather weird. I thought that perhaps during the myth of Horus and Set, while Horus is hunting Set, that he might have had 12 army leaders in those with him. However, upon reading the myths I didn't see anything about the numbers of men in his army. I am not even sure where this would have come from.
Horus walked on water? Most myths refer to him and show him riding in a boat, as is true for the Egyptian gods in general. There are some myths where Horus is transformed into a winged sun disk to fly over the Nile but this still doesn't fit the concept of walking on water.
The next one just doesn't make much sense either. "Raise El-Azur-us from the dead". I know what they are trying to get at and that is the fallacy that Osiris and Lazurus(of the Bible) are one in the same. First, I must point out that the El starting piece is not in the Egyptian language but is in the Arabic names of various locales and deities. The writer is also trying to manipulate the Egyptian name Ausar which is a name of Osiris. Horus did not resurrect anyone, and certainly not Osiris. Anubis was the god to create mummification and raise Osiris from the dead. (Sometimes with the help of Isis and/or Thoth). Remember, at the time of Osiris' murder and resurrection Horus was not yet born. Not only is this false based on mythology but it would also require a fetus/zygote to raise people from the dead. Even the Egyptians didn't have myths that off the wall.
Transfiguration may be something we could stretch our imagination to believe. As I mentioned before, Horus transformed in some myths into a sundisk to fly around. However, this usually happened in the Nile valley and marshes, not on a mountain. I can grant them that both Jesus and Horus were supposed to have changed into something glowing at some point but these are very different ideas. Jesus glowing was to signal his divinity to those around him. (That is a very paraphrased comment for the sake of brevity.) Horus transformed in order to hunt down Set and try to kill him. He was a god so no need to prove his divinity to anyone.
Titles... "The way, the truth, the light" These are titles I have seen most often used and likely created by various modern forms of Egyptian religion. You could perhaps apply "the light" to Ancient Egypt in later mythology when Horus and Ra are merged into one solar deity Ra-Horakhty. Messiah is actually an interesting title, though it is not Egyptian at all. Aside from the Christian definition, Messiah also means a zealous leader of a cause. This definition could definitely apply to Horus as he was obsessed with vengeance and murdering Set for killing Osiris... though I doubt obsession with killing someone is Christ-like. The next title includes "God's" with a capital "G" which is not an Egyptian term but a Christian one. Son of man does not work at ALL for Horus as the Pharaoh, ie man, was the son of Horus not the other way around. Lamb of God, here we are with the capital "G" god. Also, as a god of the sky, war, revenge and vengence I doubt Horus fits into the traditional "Lamb of God concept. The Word is not applicable. This concept in Ancient Egypt was Ma'at, goddess of truth. The morning star refers to Sirius which we have already addressed. The light of the world in Egypt is Ra so perhaps this could be applied to Horus after he is merged with Ra.
Crucifixion was not used by Egyptians at all. This was a Roman practice Horus never dies in the mythology and therefore cannot be resurrected.
WOW that was just the first image. I hope you are not bored or overwhelmed but I am going to continue going through the rest of these comments on the other images. Might as well finish up.
Image 2 has already been addressed in full.
On image 3 I would like to point out that Horus was born in a papyrus swamp and not a cave.
Image 4 starts out with the wrong date for the begining of Horus worship. Horus is referenced on the Narmer palette from 3000BC.
Healing of the sick and injured is highly unlikely for a god of war and vengeance. Likely, they have given Horus some of the attributes of Isis, his mother.
And at this point we are finished with dispelling some of these items that keep appearing on Facebook attributing things to Ancient Egypt that are not true. I have also seen these types of references between Osiris and Jesus as well. Here at least there are some more applicable relationships including being harmonious, kind, resurrected and so on. If you are interested in reading up on this more here are some suggested readings:

In my searching for answers here I found some other treatments of this topic that take a different approach than I do. Here is one of them. If you are interested in the topic a simple google search will turn up more.
