Yes. There are hundreds of different viruses that produce the generic "common cold" symptoms; identifying which one you have requires a genetic or antibody test. You could easily catch two viruses at once, just as easily as catching them a week apart.

But there is a particular scenario that is important for influenza epidemics: If humans and animals live in close proximity (eg pigs or ducks on a family farm), it is possible for an animal to catch (say) pig influenza and human influenza at the same time.

Because of the way influenza consists of separate strands of genetic material, it is possible for a hybrid virus to form, containing both pig and human virus. Humans may have little or no resistance to this new virus, so it could cause an epidemic.

Swine flu (pigs), Avian flu (chickens or ducks) and MERs (camels) may well have formed in this way.
