looks like at least 2 platyrhinos, and the other with it's face away....I can't tell whether that's a platy or not. Kinda looks like a cornutum or coronatum. Better pics please. Close up face shots not always very helpful for ID....where exactly did you "pick" these up?

Better do a whole lot of reading if you have three of them. I hope you have got lizard or at least reptile experience.

Start by reading the thread below this one for some information resources.
