Nice series.

Only I think the last is too close.
And on the fourth there are too background and the shadow is too strong (I think will be better redirect the light of the flash).

1: Funny
2: I really love the expression of this little model.
3: I like it especially because i don't see the face of the ugly boy near the lady.

first 2 are cute

I like the first 3. 1 and 2 are really cute, especially 1 and 3 has a beautiful look on the girls face.

1. technically the best. good framing, great skin tones, good exposure, good focus.
2. slightly underexposed. background a little busy, and I would have put her on the left side of the frame.
3. Nice expression, but the whites are blown.
4. technically the worst. Snap shot, harsh flash, out of focus eyes, no contact, just does not work for me.
5.Does not quite work for me. technically better, but the crop is just uncomfortable right under the nose.
