Hey there, I'm fairly new to the amphibian keeping hobby, however from what I've learnt so far I think you'll find that your ecclectic mix of frogs all in the same enclosure, which is too small for that many frogs in my opinion. I keep Whites and a False Tomato, both seperate, and to give an idea, I've got the Whites, which are all of 2-4cm in size, in a 39mmx38mmx49mm tank. My Tomato Frog is in an Exo Terra Faunarium for now, till he is larger.
The frogs you've got all originate from different locales and climates, for the Whites and Tomato for example, they enjoy different temperature ranges and habitats. Although the Common (I presume American Green TF) and Grey's are similar, I would still do some more research into their individual prefferences and habitats.
Also what Temps/Humidity do you have them at? I would at the very least suggest seperating them into individual species enclosures (I appreciate this isn't always a practical solution due to cost/space)
Hope this is some help
