Hi there,
On behalf your friend, thanks for writing in. Traditionally the schools will look at your highest score; the impact of asking how many times you took the test is a bit unknown. Still , at this point, your friend has already taken the test the 4th time and shown improvement, so he'll want to report his highest score. It's impact on admissions/interviews is really impossible to say -- as this will be one factor weighed in with the rest of his application.
Good luck to your friend!
