There are traditionally nine kinds of angels: Seraphim, Cherubim, Thrones, Dominions, Powers, Principalities, Virtues, Archangels and just regular Angels. However, this is in the Christian tradition, so the Jewish and Islamic traditions can vary a little — and of course, angels often appear in multiple sources in which they are listed differently. For example, Uriel is a seraph and a cherub in some of his stories and a "mere" archangel in other tales.
Angels of different types and levels perform different divine functions. Their personalities also inform what sphere of human or angelic activity they patronize, from the arts to the sciences to war to all manner of other pursuits. Then, of course, we get to the one-third of the heavenly host who walked out when God's beloved Lucifer, the Morning Star himself, stirred up a rebellion against the divine rule; they are still originally angels, but they're now also devils, playing a different role within the divine plan.
All this means that, whatever your personality, there's an angel who might be a great inspiration for you. If you love to work hard and you get plenty of recognition, but you don't see yourself as the ultimate leader, you're a Michael. If you're just into getting things done without any attention at all, you might be the record-keeper Pravuil. Tell us a little about you, and we'll figure out just what name will be inscribed for you in the angelic pantheon!
