Q: Can this be used to stop my Hot water tank from blowing out the flame on windy days?

sorry, I did not use it for the flame from HWT.

Q: can this be used on a dryer vent or will the foam seal melt?

I would say the dryer heat could damage or maybe even melt the seal. Maybe you could try removing the gasket and wrap a strip of fiberglass in it’s place.

Q: Would this help keep out bugs?

Yes it creates a barrier and only opens one way from the inside of house

Q: Would this fit between two sections of standard, 4 inch semi-rigid ducting? Looking to add to bathroom vent fan ductwork.

Yes, that's exactly how you would use it. Make sure to buy the correct HVAC aluminum (metallic) duct tape for the connection. A clamp cannot be used bc the crushing pressure would inhibit the flapper from working properly.
