Soooooooo adorable. They sound like my piggies, actually! Patches and Smudge don't like to be handled all that much either. Give them time to get used to you. Its definitely normal for them to not want to be picked up; even if they squeak for you. I like to nem guinea pigs according to their appearence, so here are some name suggestions:
Piggie #1- Cream
Piggie #2 - Ginger
Piggie #3 - Truffle(s)
