Beginner how to do questions

Hi. I have Ethereum in Coinsquare which for me was a major accomplishment.

1. How do i transfer Ethereum to Binance so that it goes to an Ethereum wallet credited to me or how do I get a wallet in Binance for that purpose..

2,. When in Binance, how do I buy BNB with the Etherium?

3. If I buy other altcoin in Binance, do i need a specific different wallet for each one of the altcoins?
