The first plant is definitely not Philo. selloum (aka Philo. bipinnatifidum), and is Monstera deliciosa. While they can superficially resemble each other, they are pretty easy to tell apart. Among other differences, Philo. selloum has deeply lobed leaves where the lobes tend to end either rounded or somewhat pointed, while the lobes of Monstera deliciosa leaves tend to be more squared off as if the outer edge of each lobe is in line with the lobes before and after it as if overall it is one continuous leaf edge (hope that makes sense). Plus, Philo. selloum does not develop the interior leaf perforations that are evident on more mature Monstera leaves.
I've grown both for quite a long time now (M. deliciosa is one of my all time favorite plants) and they are fairly simple to distinguish from one another once you are familiar with each of them.
