From what I've read of Michael Ford, he views such beings as archetypes that reflect aspects within you want to reach--a way to reach the universe through the higher self in a way.
I wouldn't personally practice Ford's rituals, but I know some who do.
But I don't believe Ford is the way you want to go. First of all, I really have a problem with the "Lucifer" aspect of Satanism because they take the entirely fabricated Christian story of "Lucifer" as a fallen angel and use it. Ancient texts of that story don't exist. Lucifer as an actual being is only truly the God of the Evening and Morning Star (Venus), also called Phospheros.
As for other authentic angels, yes! Most certainly. Everyone has their own way, but a good start is meditating on them and being open to messages in any form during that meditation (feeling, vision, thought, sound, etc). From there, you can find out which one(s) you wish to continue to work with.
