I would not underestimate how long it will take a big group to get lunch. There are not really museums in walking distance of Times Square that I can think of off the top of my head, and museums in NYC typically charge admission. You could walk to the New York Public Library, I see they have an exhibition. Or you could go to Bryant Park.
Just read you are seeing The Great Gatsby. To go to 42nd and 6th might be a stretch.
