does it have a headphone jack for a mic?

No, just a port (USB C) for charging

Can I buy 2 of the same controller and have them work independently?

It depends what "have them work independently" means. You can pair them both to the same Switch, or different Switches, or pair one to a Switch and leave the other one in a drawer or give it to your cousin for Hanukkah. Think of it like buying two of the same power drill on Amazon: they don't have to be used for the same project -- they can be used independently.
