This depends on the strength of the filtration system on the tank. On a 'normal' five gallon tank (filter turnover about 5x/hour) three or four would be a good number. On a 'five gallon tank on steroids' (I have one of these - filter turnover 12x/hour) I kept seven with no problems. If you're going to keep more than three or four, regardless of your filtration, you need to be religious about tank maintenance - 50% water change, every week. Keeping more than 6 or 7 in the tank is probably not going to work.
(For filter turnover, 5x/hour means the filter pumps 5 times the tank's volume each hour, so that would be a 25gph filter in a 5 gal tank.)

How many guppys can you have in a ten gallon tank?
Well guppys are tiny fish so i have 2 say, wait, well that depens how many other fish u have in the tank here are some examples: If u have a little pet shark, five little goldfish, 4 neon tetras, and 2 clownfish, you should have 5 guppies. If u don't have a pet shark u could have 10 guppies. (new person) Well, technically it is a ten gallon tank. If it was, say, a ten centimeter tank in height and maybe a few inches in width, then maybe ten guppies, more or less, like the person above said. But a ten gallon tank is like pet-store material, so I'd say a couple hundred guppies in a ten gallon tank.
