I don't quite get what you mean. -A vent pipe in a plumbing system is usually 1 1/2 inch ABS pipe and may extend through the roof, or may end in a AAV under a countertop.

That would depend on the fixture units each fixture has and the developed length of the vent piping
No, it won't carry the required amount of air. A vent is usually 1.5 inch and an exhaust is 4 or 5 inch.
2" VENT. Many codes say the vent can be 1/2 the size of the pipe being served but in no case less then 11/2" and considering a lead bend (toilet drain) can be 3" and the new fixtures have 1.6 GPF in lieu of the 3.5 GPF a 11/2 vent pipe is fine

The inside pipe is 3/4 inch and is a vent tube. Yes you need it.
Any vent is usually the size of the drain or waste pipe it is connected to. 3 or 4 inch on a toilet.
Sounds like your washer doesn't have a connection to your "stack pipe". As water moves through a drain pipe, it creates a vacuum behind it, the "stack pipe" or "vent pipe" is usually a pipe that goes through the roof of your house and provides an open air connection to all of your plumbing fixtures so the vacuum is provided a way to suck air rather than sucking the water out of your "P" traps or other fixtures such as your toilet. Chances are your toilet is also "sucking" from your washer, but you just don't notice it. It is also dangerous because if the washer or other fixtures are sucking water out of your "P" traps, then you may be getting methane and other sewer gases into your house. Have a pipe run from washer drain to your vent pipe and this should eliminate the problem. Be sure it connects to the vent pipe because if you ever have a sewer backup, the vent system won't allow the gray water to empty into your house through the air pipe.
