Hello and welcome to TFK
For the size of your aquarium you should be fine with adding the female platys, either six or nine. You can get away with doing a ratio of 2:1 female to male, although 3:1 would be better. What type of filtration are you running on the tank, and also do you have any live plants in the tank, if you do they will help with the filtration. A neat tool that some use when trying to figure out stocking is a calculator on aqadvisor, it does not take into account if the tank is planted or not, which will add additional filtration, but it can help in giving a general idea.
