The green one looks like a dark green clearflight pied, and the blue and yellow is a cobalt yellow face I dominant pied budgie for sure, but I can't see his wing markings well enough to determine what's causing the dilution. My guess is spangle for sure, probably opaline! Do you have any other pictures of his wings?
By the way, I moved this thread to the "Mutations and Genetics" section where it fit better
