Probably right on 1 & 2; although wish had a pic from above and one from side for each. Don't think last one is a tree frog; look at the fully webbed rear foot. Hope you had fun in there !

Hi Carlos, thx for your suggestion.
1&2 some additional pictures, pls confirm if change your mind.
3 was found in the trees (climbing quickly) and at the river in two variaties: brown and green (see picture). Although the webbed foot, it has a short and loud croak like a tree frog. Will try to upload a video, but didn't succeed so far.

Found the species: Hypsiboas boans

Hypsiboas boans, large tree frog and differs from other large tree frogs by its fully webbed last three fingers (ref Amphibians of Suriname, Paul E Ouboter & Rawien Jairam).
