Since SHTF scenario is the prime key, and I'll make a few assumptions - NO ARs are available or will remain legal, same with the ammo, they would need, IMO:
a .22 lr rifle for pests and varmints and small game
a rifle for bigger game such as deer - again, eliminating any military cartridge which might become illegal would make my choice something in the 270, 7mm, or 30-06 range
a shotgun for birds and another layer of defense - a gas gun, preferably a Beretta in 12 gauge
a handgun they can both use, and one that is not a military cartridge - something like a 38/357
for the fifth - assuming most supplies are gone or extremely limited - either a flintlock with the supplies to make their own bullets, or a bow - arrows are reusable and it can be used for stealthy game acquisition or even defense
