Yes, gourami are soft water. The platy is the harder water fish.
So now you have a 20g high (normal) with 3 dwarf rainbow, 3 panda garra. Assuming the rainbow is the Neon Dwarf, Melanotaenia praecox, which attains 2-3 inches, and should be in a group of 5-6... I would get a couple more and that's it. Check the profile for info on male/female.
Is the gourami a blue gourami, or a dwarf gourami? I would not recommend either in this tank, but at the same time if it is a must, it might manage.
