205 65 r 15 are compatible .
Yes. As long as the chains are compatible with the type and size of tires on your van.
Yes you can. The difference is minimal but handling and speedometer reading may change slightly. The manufacturer has calibrated the vehicle to the recommended size so you are better off to stick to original specs. The only reason I would make the change is if the new tires were free. Don't mix sizes on the vehicle.
Yes, they are compatible as a replacement
