One should question everything. Otherwise you stagnate with your present favourite faiths.
I don't dismiss the list you have out of hand, but it seems to me, given a spiritual realm exists and is the true reality, that spirit entities are probably all much the same "thing" and so groups of different types (as opposed to different levels of understanding) are probably unlikely.
You mention ghosts and the like. Maybe they exist, maybe they don't; but if they do there must be more than one explanation, as the ones speaking to a medium, or pushing a planchette, are unlikely to be the same as those visions of, say, a legion of Roman soldiers marching though some building a foot off the ground. Well, not unless they all meet up regularly and agree to yet another reenactment for the benefit of human witnesses each night.
