The frog appears to be Cruziohyla craspedopus, which a Google Image search shows as being either bluish or greenish (via). The lizard is described at its via as being a collared lizard.
Blue is a very unusual pigment in the animal kingdom; AFAIK, most blues are the result of structural alterations rather than pigments. These photos could be somewhat manipulated, or perhaps the specimens are variant morphs of their species. ??
