I think Lilac and Luna are double factor dominant pied blue. However, I detect a tinge of blue in their wings, which might indicate opaline. Can you post larger pics so Nev can provide definitive answer?
I think they are double factor dominant pied cobalt.
If Sunny and Snowy have black eyes with iris rings, they are double factor spangles. If they have red eyes, Sunny is lutino and Snowy is albino. If they have black eyes without iris rings, they are dark-eyed clears.
