How well does this stand up to heat? I’m looking to make coasters and I need something that can handle a cup of coffee

I'm not sure how it would handle heat. It's fantastic on canvases. And even on vases. But I know you would need to let it cure really well or glasses and cups would stick to it.

Can this be used to seal permanent marker (Sharpee type) on vinyl?

The Sealer Spray solvent may react with the ink and cause it to spread or smear. Test first on a scrap piece of vinyl to ensure you get the results you seek.

I am spraying this as a finish on a stretched canvas with acrylic paints, but don't know how long to wait for next coat?

It is best to wait until each coat is dry to the touch.

Can you use this to seal cardstock and paper? I want to use it to preserve papercraft stuff from spills or greasy finger oils.

Yes, this will work. Apply 2-3 light coats, letting dry between each coat. Test first one one to ensure you get the results you seek.
