Can you hang portraits over a sofa?
Sure, it will just look like someone is hovering over the couch.
It is ok to hang portraits over a sofa. Just make sure that you do not leave a lot of wall space between the picture and the sofa. The idea is to balance the viewer's eye between the wall and the picture.

Sure, that's where most people hang them.
