Fuse size and voltage
Needed a five amp fuse for the dash lights on my 1973 Corvette. Had to order a whole kit, including all the other fuses. The fuses arrived today and the five amp fuse says it is 125 V. The rest of the fuses are 32 V. Is this correct with a 12 V battery in a car

32 volt is what most automotive glass fuses are.
125 sounds like an appliance fuse...

An amp is an amp.
My owners manual doesn't specify 32V or 125/250V fuses. But it does specify 1AG, 3AG or SAE (SFE) fuse types. The 5A fuse for a C3 should almost certainly be the little baby 1AG (AGC). Typically lower amp 1AG fuses I've seen are rated at 125VAC.
