For me number 1 as you have light on the face - but not too much, the one thing I would add, if (as I think) you are lighting from both sides reduce one side to add some shadow/contrast on the side?
The others are just a tad too dark on the face for me. As Ed said - try a reflector - in all of them including #1?
I would also throw something dark over the sofa - the switch in the background is a little distracting.
Good efforts - keep practicing
