To repot or not?

So here are my 3 cuttings, I've been acclimating them to the outside for over a week now, and are now in 1gl containers. I live in zone 7b so we start getting some decent weather, but some nights can be a bit in the colder side, no freezing hopefully. I'm debating if I should repot or not. One will go into the ground and the other too in larger pots outside. So my question is when to report, and how big of a pot to repot in?
