No. You may leave the bar with one wire and splice the others onto it.

No you cannot. Nor can you pigtail one neutral to several others.

You CAN however do this with ground wires. Typically you can put two or three ground wires in the same terminal hole, but this does not apply with your sub-panel since the ground and neutral bars are separate.

If the circuits originate from different breakers this is not an option. The neutral pigtail will get overloaded since it will be carrying the return current from multiple circuits.

How about a larger neutral bar, or if allowed, add a second?

Actually there should be no reason to run out of neutral space in a sub-panel. There should be plenty of space considering that you would be putting in an additional ground bar to keep the grounds and neutrals separate.

Thank you guys for you help.My brother and I own different units that we are wiring and I wasn't here when they put the panels for each unit, and each panel have 4 spaces for breakers and one little bar for neutrals and I thought that I that it will be fine to put the neutrals and grounds in the same bar since is only one bar,but now I put an other bar for the grounds. Thank you again.I have a doubt about something in my neighbor house have subpenal and have a log bar and the top part has neutrals and the bottom part has the grouds is that ok? Or needs a different bar also?

They need to be separate. The Ground Bar Bolts directly on the panel, The Neutral is separate and Isolated from Ground.
How many wires are coming into the Panel? 2 hots, a neutral and ground?
