Yep both are Bothroechis schlegelii sensu lato. This species was split into eight species last year and it would require precise locality details and morphological examination to determine the actual species.
Was almost about to say it was a squam, or an African bush viper, but yeah the people above are right, the presence of the one on the bottom with those colorations is a dead ringer that it's an eyelash viper
