Your friend should speak with an experienced immiration attorney as soon as possible. While not that serious, since USCIS is now inquiring about the matter, he needs expert assistance. The differences/errors can be successfully explained, but the explanations should be done with the help of a lawyer, so as not to open or create other problems. It should alll be resolved without any major headaches, if done correctly.
Good luck to your friend!
