Depends on what type rims you want to install. New OEM rims will be very expensive and you can install after market rims for allot less.

A cheap set of 20 inch rims would not be that much worse than an expensive set of rims. The quality of the rims and brand would dictate the pricing range of the rims.
Yes, there isnt much rubber on them, so they will shorten the lifespan of the rims.
The price of 24 inch rims for your car depends on where you live. Keep in mind that cheap rims are not of high quality. Cheap rims prices start from 250 dollars.
Replacing them with new ones would be much cheaper than having the rims prepped and rechromed.
Standard 15 inch rims will fit on a 2002 Chevy Silverado. They do not allow for as much room around the rotors like larger rims.

I would think that 16" rims would fit. There isn't that much difference between the '93 and '95 Regal. I had a '93 Gran Sport which came with 16" rims and my current '93 has 15" rims. They are interchangeable.
The cost for replacing rims on four tires varies based on the type of car and the type of rims being put on. However, it normally costs about $500-$700 to purchase nice rims and have them put on the car.
Larger rims don't cause a 'loss' in horsepower or torque, just a loss in overall speed, ride comfort, etc - because the larger rims are typically heavier and require more power to rotate and because they're 'outside' of the suspension system could cause a much rougher ride. How much speed is lost or how much worse the ride gets will depend on how much heavier the rims and tires are and if they are low-profile tires (rougher ride).
