@B214 That is right. We only know about the 72 Pillars Devils. It is never said how Lucifer became a Devil (or if he was one from the beginning).

I can only guess, and since it builds partly on real legends it could be the four Maou were Angels first and became something different. With Lilith we know she was the first Wife of Adam (it is written in this wiki)...

But since I did´nt read everything it could be that some of you know more...thats why I asked...maybe in future we become more info´s.
