That is one YELLOW snow!! She's absolutely amazing! The only other snows I've seen that had that much yellow have been caramel snows; i.e. homozygous for amel, anery, and caramel.
It's said that anery masks caramel, but in a lot of caramel snows they tend to have a lot more yellow than your average snow. I'd try to test her against something that has caramel in it just to see if that's the cause of the yellow. Though I suppose she could just be a fluke, but if I was a betting man, I'd wager that she was homozygous caramel.
As for your two other snakes, Casey hit the nail on the head. They're both anerys and not ghosts. The eyes are also too light to be charcoal on either one.
