HELP what type of frog do i have?

i think they are probably tree frogs because they climb and stick to the class of the cantainer i have them in (i had them as tadpoles). They are all mostly light green with a darker stripe going on their side near their eyes with light under bellies and "sticky" feet. I live in north east pennsylvania and ive seen gray tree frogs around before. There are two of them that look a bit different though; they have a darker green colouring and stripes on their back legs. Also i have 11 of them in one container right now. they are still small but im wondering if thats safe for them. Ive been trying to feed them cut up worms, meal worms and freeze dried bloodworms but they dont seem to be eating them WILL THEY TRY TO EAT EACH OTHER??? please help i dont want any of them to get eaten. And if you do know what type they are where can i find information onhow to properly care for them. I apologize that this is so long, if you actually take the time to read the whole thing then thank you so much.
