The 50 f/1.8 and 85 f/1.8 would both do OK in this situation. You should use the lens according to focal length, as they're both pretty slow lenses, but you should be able to get at least OK shots. Shoot in Aperture priority with the lens wide open, and adjust the ISO to keep the shutter speed around 1/125-1/250 and you should do OK.
