So far only those 3 have been mentioned and all the characters are either Phoenicians, Waldenites, or Arcadians. Nothing else has been pointed out. And in Day 21, the council in the Colony wanted to block off the skybridges between Phoenix and the 2 other stations and kill their populations so the people of Phoenix could survive before Glass saves them.

I don't know if Kass Morgan will add more because the third book, Homecoming, will involve the people of the Colony coming to Earth.
