The ideal number of fish in a 5 gallon aquarium is approximately 5 fish that are of one inch length. Basicly you are allowed 1 inch of fish per gallon of water. All though though you can increase this by 1 or 2 inches with good filteration.

Different fish require different space requirements. Often a good rule to go by the one gallon-per-one inch of fish. Research about specific fish before you buy them.

You should have about 1 inch of adult fish per gallon. For instance, you may keep 5 adult fish that are 1 inch long. You may have more if some fish are bottom feeders. Fish that grow bigger than 5 inches should never be kept in a 5 gallon aquarium.

I would not recommend more than one small fish. A 5 gallon tank is a small and fragile ecosystem. Mistakes such as overfeeding and infrequent water changes will have a greater impact to this environment. This means you should be very careful to keep the system in perfect condition for the fish or move to a larger tank.

It all depends on the size of the fish you are putting into this aquarium. Judge it based on the amount of room your fish have to swim around. If it's looking too crowded as a friend to judge to see if there are too many fish in there.
