Honestly, I'd keep canonical age out of it.
For example, I don't know who the person in photo #2 is, but looks old enough to me. If it turns out that it's an "aged up version" of someone that's canonically 12... So what? In the picture they're not 12, and that's what counts.
So in my opinion 1, 3 and 5 look too young, while 2 and 4 are fine imho.
