Man, you got a handfull there! Think of it on the bright side though, you're probably fitter than most people at your age! Potato couches don't have that much overuse injuries, but they have a host of metabolic stuff that you're probably rid of. Sleep is paramount for sure, especially for rehab! I can't talk much on most of your injuries, but I can tell you what worked like a charm for plantar fasceitis: get a golf ball, and roll it under your feet while you're sitting. You can do it multiple times a day, it normally helps to relax the foot very quick, and in my case the fasceitis was gone really fast!
PS. check a book called Outlive, by Petter Attia: a ton of useful information health related, especially as our 20s seem farther away.

Get well soon! !BBH
