I wouldnt do the three above the sofa. What other walls do you have in the room? One or two above the sofa and the other or others on a different wall.

I wouldn't hang them above the sofa, stacked on either end with a table and lamp.

Show the whole room for help in placing them for the best possible outcome.

I would go with two one 2 fingers apart.

Two will look better and don’t hang too high.

The third picture will be nicer on its own on a small wall.
