In early western occult literature Baphomet and Satan were considered to look the same. And due to a lot of bad translations and other misrepresentations people just lumped them together.
Pan and Samael are very masculine.Baphomet has attributes of both sexes and is considered a whole representation of wisdom both male and female. So they are different in that way.
I have seen in Luciferianism that Samael represents male wisdom and Lilith female wisdom. So if you studied with both of them you could become like Baphomet.
Samael represents mars and weaponry so he would be a very good choice for creating and consecrating weapons. And using them in spiritual warfare.
