Help with wallets

[cb2017]

I'm having a hard time understanding wallets.  I have XRP, XLM,LTC, and ADA  on Binance exchange. In a year or two if my investments increase and I want to "cash out" for USD,  how do I do this?    I printed paper wallets for LTC and BTC.  Do I need separate paper wallets for each currency? I understand I can transfer LTC and BTC to Bitstamp and cash out for USD, but what about the alt coins that they do not support?

Sorry for the noob question but I just can't seem to grasp this even after watching youtube videos.

Thank You!  I was thinking that but just wasn't sure. So basically I would trade my alt coins such as TRON for Bitcoin on Binance, send my BTC to Bitstamp and cash out right?
