Please see these configurations of paintings to give you an idea of how you might want to design your wall.  There are many possibilities.

The white paper that all the work is lying on is approx 87 inches wide.

I believe you said the total wall width s 96 inches total which would leave room on either side when you hang.

The photos are not great they are cell phone shots taken at night but this will give you an idea.
