Yup yup what Kurt said with an emphasis on quickly. I would also recommend a trip to the vets after they are separated.

Thank you very much first of all...i try to learn all i can off the internet, but i havent learned enough obviously. I am getting 2 new tanks to seperate them into groups and wondered, how i should seperate them, im guessing by zones but i have more than 3 zones as Kurt has pointed out. And im not sure what the brown tree frog is either I got her at a very poorly kept reptile store with no title to her, and she was the only one. she has stripes sometimes and turns all colors of brown with a fairlypointy nose,big eyes, and jumps so fast you cant see her.

Eco-zones are large areas that span across continents and countries, not actual individual different habitat. A few examples, the Neotropical zone starts in southern Mexico and goes down into South America. It also includes the islands of the Caribbean. The Ethiopian zone is Sub-Sahara Africa, Madagascar, and the islands of the western Indian Ocean.
You really don't want to house animals together simply because they come from the same eco-zone. Eco-zones are made of many different habitats. The zone in which we live in, the Neoarctic zone is includes deserts, grasslands, temerate rainforest, woodlands, tundra, swamps, and so on.
You want to separate them by species. I counted six species, so you will need six enclosures.
The brown treefrog you described sounds a lot like Polypedates leucomystax. http://calphotos.berkeley.edu/cgi/im...el-lifeform=ne
