Normally 11/2" DEPENDING on developed length of piping and fittings
Yes.
No, that is why it is called a vent pipe not a soil line
Yes if the vent pipe is 4" and vertical by code and there is nothing connected between your toilet tee and where you would connect your new toilet tee. If not worried about codes then yes you can connect to a 3" vent line if no other vent lines are connected down stream. If you have a vent pipe that is less then 3" and or you have other vents connected between your old toilet tee and your new toilet tee then NO you can not connect a new tee for your toilet.
No I just checked and mine has no condensation, thanks fro asking
downstream of a closet bend within 8 ft for three inch pipe and 10 feet for 4 in pipe at least half the size of the drain... unless it is stack vented then it would be full size of the stack right
Any vent is usually the size of the drain or waste pipe it is connected to. 3 or 4 inch on a toilet.
Yes.
Who needs a toilet
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
To properly install a toilet roof vent in your home, follow these steps: Determine the location on the roof where the vent will be installed. Cut a hole in the roof for the vent pipe to pass through. Install the vent pipe through the hole, ensuring it is securely attached. Connect the vent pipe to the toilet drain pipe using appropriate fittings. Seal around the vent pipe and roof opening to prevent leaks. Test the vent to ensure proper ventilation.
The best practices for ensuring proper toilet venting in a residential plumbing system include installing a vent pipe that extends through the roof, ensuring the vent pipe is the correct size and properly sloped, and avoiding obstructions in the vent pipe to allow for proper air flow.

A toilet may bubble due to a clog in the drain pipe or a malfunctioning vent pipe. To fix this issue, you can try using a plunger to clear the clog or call a plumber to inspect and repair the vent pipe.
The toilet vent pipe is typically located on the roof of a building, above the bathroom where the toilet is installed. It helps to release sewer gases and maintain proper air pressure in the plumbing system.
1-Clear the obstruction from the vent or drain pipe 2-Be sure the vent is properly sized and graded up towards the penetration of the roof, or where it ties into the vent stack.
Normally 11/2" vent and a 3" soil line=BUT some codes want a 4" waste and then a 2" vent may be required depends on the local inspector=
