Digital photo retouching and lighting improvement

We have three different digital photographs of two gentlemen posing at a ceremony, none of which came out even decently well, mainly because of poor lighting conditions. One was them was taken with a cellphone and the other two were taken with a camera at high ISO and no flash (the flash was damaged) so they came out moved/out of focus. The goal of this project is to use these pictures, and "doctor" them so that at least one of them look acceptably decent, by fixing it up, and perhaps using other photos of these gentlemen. There are many other photos of both of them (separate) available to attempt to make this happen. The images in question are available upon request so you can assess the viability of this project.
