pretty normal, but
First of all, two weeks old is way too soon to be taken from their mother. Not sure what happened there or what a cattery is. They may be anxious because of this but seem to have bonded to you.
Usually kittens are more "in your face" in the sleeping arrangement, but usually as they grow up, want a little more detachment so will sleep at your feet. You will have to train them not to claw at you or lick you by making that uncomfortable for them like put them on the floor whenever they do it. But they will probably just jump back up and do it anyway lol. They will have to learn to trust other people slowly by slow introduction to being picked up by strangers and stuff but they may never get used to strangers after being adopted so young and just because. It is good that they have bonded to you though.
