All the members of the family look okay. The fact that the women are smiling makes them more appealing. It seems that the members of the family at least like each enough to pose for the photo, so one could guess at reasonable relationships. The clothes and setting are pretty ordinary and straight - so possibly one could guess at a very average and normal family, with all the usual kinds of problems.
I'd guess each character is neither nice nor not nice but could be either depending on circumstances and reactions.

Ah, the younger one with the beard. Yup, cool enough. You don't look bad. Probably quite a few young women would think you were hot, but always remember that the best way to attract women is to genuinely love them as whole human beings.
