"Guarding" and growling

Badger is a three year old JRT and I've had him for two years as a rescue dog. We moved in December and he had some trouble with the move but seems adjusted now. Before, it was just me and my ten year old daughter. Now there is my fiance and sometimes his three children. Badger is growling and sometimes barking aggressively at my fiance and sometimes the children when he comes upstairs to the bedroom or living room. We have crated Badger each time, but he only stops for a day or two, then the behavior repeats. He has done this with every family member except me. He is not over-aggressive in other ways, but he has tried behaviors like humping or pressuring to be petted one at a time since I've had him. The others were easy to stop, but this one is continuing. He will be submissive to Alan (very!) except in this one circumstance. Alan owned a JRT for many years, but that dog wasn't neutered and Badger is. Badger seems like he acts surprised when Alan comes upstairs or others, and seems to not recognize them. Are we not crating long enough or being strict enough with him?
