Not IMO. Dominos can reach 5.5" (nearly the size of a person's hand) and are among the nastiest of damsels. A maroon will get even larger, and has an equally bad attitude. The other three damsels may not be as aggresive as the dascyllus and maroon, but they're still fiercely territorial fish. Even in a 75g I don't know if these five would do well once half to full grown, I'm willing to bet you'd see a lot of fighting.
