Identification: Need plant identification

if u can figure these out.. that would be great i know one of them but cant remember the name.. thank you!

 

1 initially i thought pencil cactus - then i noticed that one leaf at the bottom - that looks like some type of epiphyllum.

2 is chinese evergreen. 3 might be also.

4 is an epi

 

actually, 3 might be peace lily.

 

1. is a pencil cactus that leaf is just from the epi

 

I agree with cody and joclyn and just to elaborate
2. Aglonema
3. Spathiphyllum
4. Epiphyllum
