I'm lousy at greywing vs. clearwing so I'll wait for the experts to identify Princess (foreground) and Kiki (background). Why is Princess' vent dirty?
Zohan is recessive pied sky blue.
I think the green male might be opaline grey-green cinnamon????
Gandalf looks normal cobalt violet.

The picture of Kiki and Princess is not clear enough to tell their mutations. They could be clearwing or greywing or even spangle. The only thing I can tell for sure is that they are both opaline and blue

Zohan is a recessive pied sky blue. The yellow bird is a grey green and he could be either greywing, cinnamon or clearwing but we need a better picture to be able to tell

Gandalf is cobalt and he could be opaline but we need a better picture to be sure. It is possible that he is violet but the color in that picture is far from natural
