I'm new to the mountain biking and when I went out riding my first ride with my brand new Schwinn Axum Comp 29", the derailleur I believe it's called, got tangled up in my spokes somehow. My spokes in the rim didn't get messed up thank the Lord. But I believe it did bend the hanger I believe it's called and the derailleur went from facing straight down, to straight up. If anyone has some links where I can get the parts I'd highly appreciate it. I'm trying go as cheap as possible atm. As I just spent $400 on this bike a couple of days ago. The cheap fix is just going to be a temporary fix until I can upgrade it to a more professional, High Grade parts.

It’s quite hard to see in your pictures, but you certainly need a new derailleur hanger and a replacement derailleur.
You should be able to find the right hanger here: https://derailleurhanger.com/?utm_source=google&utm_medium=cpc&gad_source=1&gad_campaignid=1411609836&gbraid=0AAAAAD7NchluTM0sXAqKjeWi12r6-EsoN
You could pick up a used derailleur on eBay. The one in your bike is a brand I’ve never heard of, so you might need to do a little research about compatibility with the shifter. I *suspect* it pulls the same amount of cable as a Shimano MTB shifter, but that’s a guess. Ensure the derailleur can handle the number of sprockets on your cassette (don’t buy a 10-speed derailleur and fit it to a 12-speed system).
You’ll almost certainly need a new chain. Don’t buy it used or from Amazon, eBay, AliExpress etc. Again, make sure it’s a chain designed for the number of speeds on your cassette.
Unless you hit your derailleur on something, the problem was probably caused by poor adjustment of the Low limit screw (marked L on your derailleur). It controls how far towards the spokes (as you shift into low gear) the derailleur can move. It’s should be carefully adjusted so that the derailleur’s upper pulley wheel exactly lines up with the largest sprocket and cannot move further. Make that adjustment on your replacement derailleur before you put the chain on.
There are loads of great videos about installing derailleur, chain etc. on Park Tool’s YouTube channel.
Good luck.
