They won't repeat the Aliea Arc, and I highly doubt any of those people you listed will leave their schools to join Raimon. (Except for Minamisawa)

For now let's enjoy the rest of Season 1 as the upcoming arc is going to be amazing. No one in Raimon will become an antagonist lol. The only thing that's going to be repeated in GO is the Challenge To The World arc.
