What are main features of binance default wallet?

I have several doubts about Binance wallets

  1. How is called binance default wallet?
  2. Is the binance default wallet that Trust wallet?
  3. This wallet accepts several cryptos into the same address?
  4. The same address can be used for deposit and withdrawal?
  5. A binance user can have several wallets for the same currency?

Thanks in advance
