What should I do with this set up? (Repost)

(repost because my original post didn't seem to have all the pictures and idk how to edit a post on mobile)

Set was gifted by and older lady my dad did work for after she moved, does anyone know what I should do with this, I live in a small studio and probably shouldnt make too much noise anyways, and my dad's living room as about 20ft by 15ft. Does anyone have any recommendations on what's usable for him and what he should probably sell, also if you know the estimated value?

Also I'm sorry if this post is incorrect in any way I'm not big on posting on Reddit or an audiophile, if you can recommend better subreddits to post on instead l'll also appreciate that, thank you.
