It's only been a couple days. She's in a completely new environment, with new people, and separated from her mom and littermates. She's probably stressed and confused, so while I can understand that this is alarming when she's not acting how you expected, give her some time.
It might sound counterintuitive, but I'd step back from formal training whatsoever for a little while. Work on teaching her that great things come from you. Hand feed her without expecting her to perform cues, spend time sitting with her and letting her explore on her own without pressuring her to interact with you. Watch her body language carefully and try not to overwhelm her with attention or expectations while she's still figuring things out. This might just be a couple days, or a couple weeks, depending on her temperament, but this will help build a bond with her and teach her that you respect her needs and are the source of good things.
For biting, some dogs respond well to a yelp, but others think it's exciting. Since it seems to amp her up, instead immediately remove yourself. A hard bite means you stand up and turn around, refusing to look at her for a few seconds, before going back to interacting with her. Rinse and repeat if she bites again. If she continues to bite at your feet/pant legs when you turn away, you may have to change this to stepping over a barrier you set up - like a baby gate or playpen - so she absolutely can't continue the "game". This takes time and consistency, and you may find you're doing it multiple times in a row. If she's absolutely not stopping after 3-4 times (assuming she also has appropriate things to bite and chew on, like toys), it's fine to just end interaction entirely and give her a break in a puppy-safe area (crate, pen, puppy-proofed room, etc.). Like toddlers, sometimes puppies turn into little terrors when they're overtired and you just have to give them a quiet space to nap.
I'm assuming she's a pretty young puppy? If there's a way to not take her out on leash for a few days while she's adjusting, do it. If she needs to be leashed for potty trips, try to make them really short and don't expect much in terms of leash manners (maybe carry her to a spot, wait for her to potty, reward, then carry her in). When she's more comfortable with you, you can start getting her used to the leash in the house, letting her drag a short, lightweight leash to get used to the sensation (supervised only! She could get caught on something or tangled otherwise). You can also try teaching her that giving into leash pressure is a good thing by working on the Silky Leash protocol - lots of articles and YouTube videos about it out there. I believe Grisha Stewart was the one who popularized it under that name. Otherwise, again, it's a lot of consistency, not giving in when she pulls, and rewarding (food at first, praise works for some dogs but they need a solid bond with you first) when she keeps the leash slack.
Some harnesses designed for hunting or tracking will have an extra ring in the front, on the chest, if you have access to these kinds of harnesses. Connecting a leash here will make pulling a little more difficult, even though they're not marketed as 'no pull'. But I'd start with just getting her used to the lead and leash pressure in baby steps, and see how she settles in over the next couple weeks.
