Not sure if you're looking for C&C? But here's my nits, FWIW.
They all have a magenta hue, at least on my monitor. And in #1, the girl's face looks orange compared to the rest of the scene.
#2 could stand to be straightened up, it leans a little right. WB looks cool - look at the boy's legs. But again with the girl looking orange in comparison.
#3 - best of the set, IMO
#4 - WB is too cool (to me)
#5 - better color balance but I agree with the precarious-looking perch on the high chair comment.
Overall - cute girl, not a bad set. They are all a bit hot/overexposed IMO, but I've also been told I tend to underexpose (and with that, tend to lean too warm) so take that FWIW lol. They lack contrast - there's no depth or shadowing on the faces, and in #3 I'd like to see more contrast overall... is that wagon wheel supposed to be straight red? It looks a bit pinkish-red to me, possibly going on with the whole magenta-hue I noticed in every picture.
I don't dislike them at all. These are just things I noticed
