Help! I need to identify these plants!

If you know your houseplants (and common condolence basket plants), please comment to assist me in identifying and caring for these ones. I am going to separate them soon because I doubt they share the same needs and really want them to thrive.  So far I think I have a peace lily identified... just not sure what its needs are and the internet tends to have conflicting ideas.

 

Thank you.  As I find identification and care instructions for the plants, I'll start posting them.
