10 Gallon 5 gallon and Meduim bowls?

I have all these right now. I also rescued two guppy fry from petco that turned out to be a pair. I would like to breed these .. Can i breed them in the five gallon, grow out fry in these : a href="http://www.petco.com/product/5914/Lee-s-Kritter-Keepers.aspx" rel="nofollow"http://www.petco.com/product/5914/Lee-s-…/a and have adults in the ten gallon. Culling and giving away the slower growers and mixed colors. What is the max in the ten gallon. And what a trio in the 5 gallon? how long for the fry in the containers?
