Satan is Ptah, Hep and aspects of Osiris as well (sharing this with Osiris Himself), and Dionysus, Poseidon, Phanes, Pan, Hephaistos, Prometheus, Phosphoros and Hesperos and certain specific aspects of Hades (likewise, with Nergal) and Hermes (likewise, with Thoth). Under the name of Dionysus, He is called 'master of the Zodiac wheel'.
Beelzebub and Satan also blend in many regards because this relates to the mysteries of the universe. This is why Dionysus is called 'Twice-Born Zeus'. There is also the trifecta of Zeus, Hades and Poseidon Helikonios, or Zeus, Hades-Dionysus and Poseidon. This was ripped off into the trinity filth.
Satan's functions can be too complex to just be put into one God. As far as Wotan is concerned, the mythology can be very confusing for this reason.
I am pretty sure Eisus is Satan in the Celtic pantheon because his functions are near-identical to Wotan, both Wotan and Eisus overlap with Poseidon and the Romans named both Wotan and Eisus as 'Mercury' but I don't know for sure.
