Yes, the sentence "Could you please stop mocking me?" is grammatically correct. It is a polite way to request someone to cease making fun of or imitating you.
the person will stop until he/she wants to or u could message them
It is Can you please stop
Could be. Could also mean he likes what you're giving, and if you stop giving, he won't be back. Could also mean you're the only place he can get it.
