The first 4 I think is: greygreen, light green; light green and grey.
The one in the second pic is a beauty: I'll go for RP, but it could be a combo between RP and dom pied. It looks like a male to me - the cere is pinkish and that's another indication that it is a Rp.
But I've been wrong so many times. Maybe some of the experts will tell us.
1: normal gray green
2: normal dark green (since you have the flash on, it will make the colors look brighter than they really are, so though the photo looks light green, I'm guessing dark green because you used the flash)
3: normal dark green, maybe light green.
4: normal gray
A picture without the flash in natural light will help confirm these guesses.
I can't tell for sure without a pic of the belly. He's either a recessive pied or double factor dominant pied. He's a baby so I can't go by the cere or eyes. He's violet.
