I think you guys are confusing a few things. The names you are using are not in the Egyptian language but in Ancient Greek.
Set in Egyptian is Sutekh.
Osiris in Egyptian is Ausar.
Horus is quite tricky as they haven't been able to find any pronunciation of the original Egyptian, as far as I know.
Satan is, in my opinion, Ptah. Ptah is the same in Egyptian. One can also understand it from his role in Ancient Egyptian mythology and also by how his staff is depicted: a unique combination of the was, the ankh and the djedh. This harbours a resemblance to his Sumerian name.
