I'm afraid you really need supervision with something like this. I don't know how aggressive your horse is actually being, and how much of a fight he will put up if challenged. Some horses (mine, for example) will smash you against walls or rear and strike with his front hooves if someone tries to "be the boss" and I don't want you having that happen.
All I can say is carry a dressage whip when you go into the stable and keep it between you and him, and give him a good pop with it whenever he tries to do something (not a tickle, not a tap, a good smack - he may kick out or swing round with his teeth to argue back s. Never turn your back on him, never take a step back when he has a go or he could press his advantage.
But please please please get some supervision - surely there is someone with experience at the barn?
