Neat find. Also looking at the original image, just to the right and below this area, note that there are three very young craters, and at least one other closer to the bottom of the strip. They are young, that is, for the moon, because they are much brighter and have bright "rays" coming from them.
They are far more recent than any of the surface around them. The objects you imaged, on the other hand are much older, as gauged by the pits (small craters) on them. They are probably just natural blocks of rock, tossed out of some massive crater impact elsewhere on the moon, but oh how intriguing!
