The car is fitted with air conditioning but the air exchange unit does not work,thus there is no way outsideair can enter unless the windows are down.

Though smart cookie is correct, lets make the assumption he is not.
First of all, we need the length, bredth and height of the insides of the car, and multiplying them all will tell you approximately how much oxygen the car will hold, assuming 1l is 1000cm^3. and 1cm^3 is 1ml.
The average gasp of breath is 600ml, and we breath about 16 times per minute, so use the formula:
breaths=(lxbxh)/600
time=breaths/16
However, a car is not sealed completely. There are always holes, vents etc. If you need proof, drive a car into a deep pon with the windows up, and you will see that water seeps inside, even though the windows are shut.

I don't know where you are but the vent control should have a fresh air and recycle position. If this control is put in the fresh air position then it will not matter whether the air-con works or not an air will be forced through the car by the movement. Modern cars usually have a vent near the back to let the air out again so opening the window should not be necessary unless you want more air for cooling.

Never - the car is not sealed. You still have fresh air vents, air will pass by the fans even if they aren't working.

The door seals are barely water tight let alone air tight.
YOU HAVE NOTHING TO WORRY ABOUT.
