I think the second one may be a RB. The ears bigger than average, but still much a RB kitten look. Probably even a good RB (often difficult to see on kittens)
The first Im more hesitating for. If yes so "pet quality" as they say. Although it may be difficult to say in kittens, not seldom they do get better as adult. Both eyes (should be livid green!) can get better with time, and also this doom-alike skull can get more even.
But the fur seems OK. Not just grey "blue" but also a silvery shiming to it.
But remember. No papers, in american called for pedigree = no real purebreed.
And also pet quality RB "should" have papers.
