Hello! They sound like a lovely pair of bunnies.
I would continue as you are, let them come to you not you go to them. They sound inquisitive and interested but they're still in the settling stage, they will gain confidence with time
Not many rabbits like being picked up, being prey animals and all. So this will most likely be something they will dislike and as they're still new and settling down, I would personally not do it. My Binky (had for almost 5 years now, time flies!) still will not let me stroke her unless it's completely on her terms, and I've come to accept that and ignore her grunts and thumps when she's having an off day
Keep doing what you're doing, sounds like a wonderful way to introduce them into the family x
