I agree about the second budgie but the first has silver cheek patches and no actual markings or body colour. It may just be the picture though as it looks like it isn't true to life. However, I would guess df spangle or dark eyed clear from that image. Perhaps you could get one in natural light for us?
They look like two beautiful little girls to me. While it is difficult to see your baby's markings (I have noticed this with some greywing babies I've had), I would have to agree with StarlingWings on the mutations she has.
Unless the photo is very different from reality, the yellow bird has white flights and a white tail. That is not a greywing trait, neither is silver cheek patches even in dilutes so I don't think it is that either.
