Identification: Is this a setcreasea purpurea boom?

I am trying to identify some of the houseplants I have. I would like to learn more about them. I have attached photos. Thanks so much!

 

Ok Max,
#1 Wandering Jew, I think
#2 Looks like a pepperomia
#3 don't know
#4 Dieffenbachia or dumb cane

Can you get a better picture of the leaves on Plant #3?

 

Here are more pictures of #3... hope it helps.

 

That is Hypoestes and yes, the first one is Tradescantia pallida, synonym Setcreasea purpurea (wandering Jew).

Hypoestes is not a trailing plant. Yours must want more sunlight.

 

Actually I planted a newer plant amongs the older one, and when I started my new job, my boyfriend didn't water it enough. It's a little better now, it was almost dead :(
