Researching the characters I saw that some of them actually have names other than Medusa, Black Bolt, Crystal, ect., but apparently those actually are there names here. I find it a little ironic that they seem to be downplaying a lot of other more fantastic elements, but then just left them with their superhero names.
In case anyone is curious here are the names from the comics:
Black Bolt = Blackagar Boltagon
Medusa = Medusalith Amaquelin
Crystal = Crystalia Amaquelin
Others just have last names added onto their superhero name.
Maximus is Maximus Boltagon, Gorgon is Gorgon Pentragon, and Karnak is Karnak Mander Azur. Triton is just Triton.
