Goomba looks like a dark grey yellow face. Not sure if I or II, can you get a pic of his back? The white looks like a cobalt recessive pied yellow face. But that is just because if he yellowmn the tail. I assume the face has yellow too. I want them both! Any chance you live near Missouri?! That is a seriously beautiful clutch! They could all have different fathers. Even though only one male helped care for them, she could have mated with several. The sperm can live inside her for a few weeks. You know she is split for recessive pied at least.
Goomba(in the first pic) is a mauve yellowface normal He looks like he might be carrying violet as well. It will be much easier to tell what yellowface mutation after his first molt, but I would guess sf yellowface II.
