How do NES games keep track of multiple instances of entities?

Hello. I've recently started researching NES Homebrew development and I now have a decent grasp on 6502 asm and the NES hardware, but one thing still perplexes me. How do NES games keep track of multiple instances of entites? I know how to do this in higher level languages (using classes or structs and looping through an array of these objects) but how would you implement something like that for NES in 6502 asm?

One more question. How would I detect collision between sprites and background tiles?

Thanks.
