As I once had a band project, Shadows Prophecy. I actually had a band once, called Another Face (which didn't last at all, and anyway the name doesn't sound so good in english).
The number of player depends on which music style you wants to play. Usually, 3 or 4 is just fine, but most the bands I listen to have 6: vocals, 2 guitars, bass, drums and keyboard.
