Well, we have decided to split the kittens up into two sets of two - primarily because two of them are just not taming down - in fact one is VERY aggressive. so am hoping that smaller groups might help with this.

The black girl and large tabby boy are quite happy to be stroked now and are not showing any signs of aggression - however the two tabbies are very ferocious still.

If they will not eventually tame down then they will have to be spayed and housed somewhere outside where they can effectively live as wild animals. As they say - you can't win 'em all!
