neutral wires


can neutral wires from different circuits be tied together, so that only one wire is added to the nuetral bar?

As a general rule, no.

But in older panels with limited space on the neutral bars, it is a much preferred method to placing two neutrals under one screw (a NEC violation). Make sure the two circuits are on different hot legs so the total load on the neutral pigtail is the difference between the circuit loads and not the sum.

How about absolutely NOT. Even if you are using two separate circuits on different legs of the service.

It's an even more preferred method to either quit adding circuits that your panel can't hold...or change the panel to one with more capacity.
