Put the neutered male in with her in her half and let him acclimate to her for a few weeks - he's going to be the most submissive. Once that happens add one of the kids - keep going until you get to the mother who'll be the most 'feral' of the group, but by that time she'll have no support from the others and normalcy will return.
IF by any chance you reach a point where the newly introduced Sugar Glider fights her a lot and won't calm down, skip that one and go to the next. You may end up with two 'colonies', just make sure she has at least one Sugar Glider with her - they need companionship...
