Yes you can, most phone allows you to have two people on call. You can put one on hold and make another call and get to talk to them.
It depends on what type of phone that you have.

Yes it's called a three way but not all phones do three way
You must be a subscriber of 3 way calling with your phone carrier to be able to make multiple calls at the same time
You can make three way calls usually just by dialing the number while your talking although only some phones are not capable of making three way calls at all
