I had an old camera with film in it from at least 1995 or earlier and had it developed. there are some treasured pictures there, but they are extremely faint. is there any way to get these developed so they would be enhanced and look like normal photos?
No. Film can only be developed once.
What you should do instead is scan the negatives using the highest bit-depth film scanner you can find. Many photo stores can do this if you do not have access to one. Scanners can do 48 bits-per-pixel or even 96 bits-per-pixel now. Some high-resolution scanners can use a special transparency adapter add-on but a specialized model is best.
You will then use an application, lets say Photoshop or Lightroom, to bring out the details and increase the contrast. Given you will be doing this digitally, you will have plenty of chances for trial-and-error until you get the look which satisfies you the most. If you use Lightroom there is any easy way to apply the same transformation to all your images in one go.
EDIT: As noted by @PatFarrell, you can also scan the prints. I recommend scanning the negatives because you already have lost information going from negatives to prints, particularly when it comes to dynamic-range which is your primary concern to recover faded images.
Once film is developed, there is no more to re-develop. You can, however, scan the photos in and use the standard photo post processing packages (lightroom, photoshop, etc.) to adjust the images, and the results can be huge improvements.
