I'd leave them all. The fruit that are full size look like most should ripen fine, mine did. The few individual bananas that are black will rot, but the rest look good. The stalks that have pushed a bloom or are close can usually get enough energy from the clump if you let an extra one or two smaller shoots grow from the bottom to bring energy in to he shared corm. I'm in central Florida and will only cull the plants whose trunks rot from cold damage. If only the leaves were damaged they bounce back pretty fast and I leave them.
