Typically just like you would find a leak in a cooking gas line. Get some dish detergent (about a teaspoon full and mix it with some water in a spray bottle. Inflate the system then go point to point where the hoses connect to the bags and fill lines. When you see bubbles, you have found the leak. If that does not work, spray each bag until you see bubbles.

Nope. You probably have a leak in the system such as a damaged air line or a bad air bag/shock. Mix up a small spray bottle of dish soap and water and spray all the lines, fittings and air bags. This should help you find the source of the leak.
Never heard of them being able to be changed.
The air bag suspension is damaged. This could be a single air bag on one or the other side of the car or the pump is bad or leaking. Also, the hoses could have developed a leak. If you can turn the car on and the back of the car raises, you may have a leak in the system.
Lincoln Town Car uses air suspension on the rear wheels. There is a motor plumping air to the suspension air bag. If the motor runs for too long or too frequent it will trigger the suspension light. Usually it means there is a leak on the air bag, that is why it keeps plumping. The life time of the air bag is about 10 years. I changed my 1996 TC on 2006. Bought online for $100 each (aftermarket). You can simply apply some sop water on the air bag and see if it leaks (just like the way you check tire leaks). If you don't replace the bag the motor might burn out soon. The air bag is not hard to replace. No special tool needed, but you have to jack the car very high. So I don't think you need to do the "non-air" conversion.
No. Buy a new bag.
