Welcome aboard. I see reed frogs all the time over at Kingsnake.com/classifieds. Snakes are the easiest of the herps to keep, so I can't understand how you had problems. As far as I know, all the pygmy chameleons, Brookesia sp, are imported/wild caught specimens that have a real hard time adjusting to captivity.

For your taxonomic information; Bombina orientalis is the most common of the fire-bellied toads in the US pet trade, so most likely that's what yours are. They can either be on the brown side or bright green.
Your Egyptian toad is most likely Pseudepidalea viridis, the Eurasian green toad. Most, if not all, specimens are wild caught out if Egypt. The species range surrounds the Mediterranean Sea and extends eastward at least to Armenia.
The peacock or big-eyed treefrog, Leptopelis vermiculatus is a native of East Africa. Juvenile are beautiful, being emerald green with black reticulations dorsally and having white patches around toward the undersides of the arms, legs, and upper lip. The fingers and toes are white with black bands. Unfortunately, they don't stay this way. To see an adult go to my photo albums, I have a photo of one there.
The Great Plains toad is Anaxyrus cognatus and the red-eyed leaf frog is Agalychnis callidryas. Oh and the argus reed frog, oddly enough, is Hyperolius argus. Your pac-man most likely was Ceratophrys cranwelli.
