Sounds like she is just trying to play; puppies bite ears and legs when they are playing. She will probably mature out of some of that. In the meantime, you need to give Hunter a place where he can get away from all the puppy nonsense so that he does not get cranky with her. Ringo had a high stool that he could climb up on and look out the window; Lucy was too small to get up there. That was a godsend.
Be sure and play lots with her and walk her if she is old enough to get rid of some of that excess energy; she might not be so eager to bite your other dog's ears and feet. He will probably continue to put her in her place if she does not settle down some.
You need some REALLY GOOD high-value treats to help with the potty training; little bites of cooked chicken - something she really likes and does not get much.
Stay with her in the yard and when she finally does something; I mean the SECOND she is finished - treat and praise her like crazy. If she does not go when you take her out; place her in her crates for a little while; then take her out again. If she pees, treat and praise like crazy. If not, back in the crate.
Good Luck
