First, welcome to Tropical Fish Keeping forum.
Second, I moved this post out of the existing thread you posted in and started its own new thread. It was not directly related to the other thread, plus it will get more notice on its own.
Third, to your question.
This is something that can't be directly answered because several factors impact the number of fish that an aquarium can support safely. The size of the fish (at maturity, not when you get them), the species (some need groups, some have behavioural issues, etc), the tank itself (not only the size with water volume, but live plants and decor), along with your filter and water changes.
As you already seem to have the fish, if you tell us which they are and how many of each, and indicate if you have live plants and how the tank is set up, one of us will be able to provide an answer.
Byron.
