Its quite hard to tell from the photos what sex they are, especially the second one because recessive pieds are harder to sex.
From what i can see, the first budgie is a Yellowface type two dominant pied grey male. The way you can tell its a male is by carefully inspecting the cere (fleshy coloured nose part above the beak). If there is pure white around the nostrils it is a girl, if it is a pink, blue or purpley pink colour with no white around the nostrils its likely a boy.
The second bird looks to be a Yellowface type two recessive pied sky blue. I couldnt give you a fair comment on the sex of this bird without a close up of the cere and head.
i dont know their mutations it seems it has a lot of info about their mutations from the looks of it..
i think the 1st budgie w/ a yellow clear wing is a male (btw its beak is a bit small and sharp? or maybe its just the camera?)
the 2nd budgie that looks like a pied cinnamon is a female.. male pieds mostly have pink ceres and females have white rings around that nostrils.
i hope i helped.. have a great day!
BTW YOUR BUDGIES ARE UNIQUE.. i find it hard to completely state their mutations
i love them so much!..
