Lighting fixes on 5 images

I need the lighting on the 5 images here fixed so the subjects don't look like they're being doused in projector light:

Basically the colours of their clothes in the top half of the photos should match the colours of their clothes in the bottom half and their skin should also appear unlit my the projector. It would also be good if you could correct the background colour of the projections behind (the background should be white) although this shouldn't be the main focus of the project.

If you think you can fix them let me know!
