And it is possible to beat the game with only 3 characters. So getting all the others are, as you mentioned, optional. Sure gogo and umaro dont have back stories and arent considered "main characters" but they are still joinable characters that once you have, you always have. They are optional as well, you just dont find out much, at all, about their history.
