My Moms Fiddle Leaf Fig 😅

Hey so I’ve been getting into plants and my mom has plants but many are struggling. This fiddle looks like 4 in one pot which I already recognize is stunting growth. I guess just wtf do I do ? Should I repot individually and throw out the ones with no leaves ? Or try to bring all back to life? What soil mix would you guys recommend and what looks to have been the main problem with these guys ? I honestly have no idea how much it’s watered or when it was last potted but the soil is loose and airy and there’s a slight dampness about a fingers depth down. It’s in a room with lots of bright indirect light (not sure how direct during the day while I’m at school ) so I’m hoping that’s not the problem. Thanks for anyone who took the time to read this and post a comment .
