For your Dumpy and Green Tree Frogs I would suggest Good stiff leaf Bromeliads, Pothos, and Snake plants which are all easy to grow and your basic Daylight CFL bulbs will provide enough lighting to support them. All can be obtained at local florist shop and your bigger box hardware stores.

Dumpy's will usually trash many smaller terrarium plants just due to their aggressive eating nature and their size.

As for your pacman, hopefully someone else will chime in here.
