James Patterson's Alex Cross novels are written with Cross in first person and everyone else in third. He gets away with it because he can get away with anything.
If this is your first, or early, attempt at novel writing, I'd advise using third person all the way through. It is the least difficult, and will force you to stay in one person's POV throughout the story. If you absolutely, positively, must switch to another person's POV, stay in third person. Don't make the switch because it's easier for you to tell the tale.
