well your car needs a new body kit because that contributes to the temperature of the car
Your car is starting to overheat or your thermostat is going out. Get it checked.
Yes, because your vehicle will overheat.

Yes the temperature gauge will still work. If it stuck open the car will run cool. If it is stuck closed the car will overheat.
If you temperature gauge is going up and down then you may have a problem with your sensor. You should take your car to a professional to ensure that you don't overheat your car.
no, it will not
Either the car will overheat (stuck shut) or the car will never reach normal temperature(stuck open). If there is no reading on the guage the temperature sender in the engine cylinder head is likely to be faulty.
no
Turning the heat on would actually lower the engine temperature. It's a well known trick if your car starts to overheat. Having the A/C on causes a power loss to operate the compressor, which would also cause engine temperature to go up due to the hot air from the condensor going through the radiator.
sometime the fan do not work which can cause the car to overheat. Also it can be a fuse for the fan. Check your thermostat.
