The two types of treefrogs you mention will do fine together but no way would I keep a snake with them or snake with anoles both will live in fear and the anoles will just hide at best be stressed all the time.

Tree frogs need it more humid than anoles because even in places where anoles are found they bask and dry off completely for hours while treefrogs hide during dry day and out during humid nights.

House geckos the common small type and anoles work well or treefrogs of similiar size (NEVER Cuban tree they eat same size frogs) but no way would add any snake.

I don't know difference between green snakes as think 2 types but have seen here green snakes in yard grab anoles.
