First off, DEEP BREATH! Inhale...Exhale. PHEW!
Okay now think about this rationally. I am building off of what SpeedRacer said.
You have had her only a few days, she's in a stall, new environment, with no one she trusts. Give her some time. Almost ALL horses "freak" when they are moved, unless they are with someone they trust. Just the fact that she calms down when you are with her is a good sign.
The biting your mare thing, of course that is going to happen. If they have not yet worked out their pecking order, they will find ways to harass one another, its how they figure out the herd order.
So take another deep breath. Her behavior is not necessarily out of the ordinary. When I originally purchased my gelding, he tried to bite me, ran through my lead, broke a fence and freaked out BIG time, running around like a maniac, and I hadn't even gotten him in a stall yet! When I moved him late, after MONTHS of working with him to where those bad habits were all gone, he was still a butt (although not nearly as bad) for a few days after the move, coming up with old bad habits. He calmed down with some exercise in a big open pasture and some time to adjust, and went back to remembering his training.
My advice? Put her in a pasture of some sort if possible, or a dry lot where she can move around and get to know her surroundings. IF at all possible, put her NEXT to her soon-to-be pasture mates over a fence. They can work most of it out over a fence. Before letting her free, lead her around the pasture, show her where her fences and boundaries are, and maybe throw her a flake of hay. Stay with her for a little while, let her blow off some steam and go from there.
Keep in mind, some horses are COMPLETELY different in stalls than they are let out to pasture. My mare used to go stir crazy in a stall, but was an angel in the pasture. Just because she is "mean" to the others in a stall doesn't mean she is going to be a complete jerk when she is put to pasture with them.
Give her time, and do not over think it. She is an animal adjusting and she needs time to just work it through in her brain. Don't expect much for a while, but keep working with her to earn her trust as she gets over a stressful time.
