Can you checkmate while in check?

Was reading a book, and in the book the characters were playing chess. Character #1 checks Character #2, then Character #2 checkmates Character #1. Wasn't sure if that was a legal move, but I think it is right?

It's possible. The player could block check and also deliver mate via a discovery.

but what if the move doesn't block check but delivers mate?

When you are in check, the only legal moves are ones that get you out of check.

The logic behind it being that if Kings were captured, then the sequence of play would be: Player 1 gives check, Player 2 gives "mate", Player 1 captures King.

When you are in check, you have 3 options: 1) capture the checking piece, 2) block the check, or 3) move the king. There are special positions where it is possible to do one of those and deliver check mate to your opponent, but whatever you do must deal with the check. You cannot checkmate your opponent while you are still in check.

No, you always have to answer the check and can never leave the king in check.

A move that leaves you in check is illegal.

It would be possible if the piece blocking the first player's check also revealed a discovered check, or the first player's checking piece is pinned so it cannot capture the piece that blocks the check and checks the opponent.

Not possible

This was an interesting puzzle I came across. If Qe5+,, then black can block with the bishop, discovering mate.

Any position with both kings in check is an illegal position and has been reached with an illegal move. But of course, it can be legal to give checkmate with a move you make to get yourself out of check.
