Hi Sue,
I would recomend keeping the red-eyed tree frog seperate, especially if it's wild-caught. They are more sensative than the species you keep now and would not work well when kept together with them. Frogs do not need company and often do best in captivity when they are alone. Another frog means more competition for food and territory, not a friend to socialize with.
Regarding the other species, it would be best to seperate the White's tree frogs and the anoles. Not because the anoles will eat the frogs as suggested in the reply below, but because the frogs have potential to eat the anoles. White's tree frogs have large mouths and are known to eat everything from your average cricket to fuzzy mice. If your anoles are adults rather than smaller juveniles there is probably less of a chance that the frog will try to eat them, but there are other reasons to keep them seperate such as they both do best in slightly different captive environments and they both eat different sized food items. Good luck,
