There is quite alot of animal species that can store sperm from one mating
and use it later ,guppies etc and some reptiles for exampel.Is this some thing that ocur with shrimps and crayfish as well?

Not with any of the shrimp I've raised like most of the ones discussed here. I can't say about crays. With RCS and Amanos, et. al. if there is no male present, the eggs drop off in a couple of days.

If a female shrimp has to molt just before mating, I wonder if it's even physically possible for her to keep old sperm from getting shucked off with her old exoskeleton.

Shrimp species cannot. Crays can for a few months, at least some species, if not all.
