Generally speaking is it required for homes to have more than one exit?
Egress is what you’re really talking about.
It can be a bit complicated given local codes etc.
But yes, 2 should be minimum by door or by window/fire escape.
I would suggest doing more research based on your locale.

No, but sleeping rooms do. Generally the door + 1 egress window.
Yes it is mandatory to have front door and backward door which works as ventilation. It makes your room air clean and fresh. So make more than one exit for good air circulation.
