Well, what you have there is a universal GM key. You see, GM 6 pin locks, used from about 1967 until about 1995, in most models, used a 6 pin key. Now there are 8 different keys, 4 door, and 4 ignition.
Ignition keys are labeled A, C, E, J. Doors are B, D, H, K. The keys you have there will slide into any of those keyways.
Are they try-out keys....probably, and are probably home made. I can tell there would be far more than 50 combination needed to work on all locks. Also, they look to be cut rather badly, and I can tell you that the last key for sure has a cut that is way to deep to work on anything.
