Well the Mural gems are obviously Blue Diamond, Yellow Diamond, and White Diamond.

The statues from Attack the Light are Diamond fusions (of all three Diamonds)

The holgram gem from the Rebellion is obviously Jasper.

Maybe the Lunar Sea Spire gems are other gems who survived the Rebellion with the CG before they became (possinly) corrupted gems. (And the two fusions in that ep are maybe fusions of some of them.)
