Based on what happened (oil light coming on at speed), I think you make have done some engine damage.

To know, you will need to get a compression test. That will tell you if the cylinder walls were damaged from a lack of oil. Knocking noises will tell you the bearings were damaged.

As a refresher for any new Ninja owner -

The oil level needs to be checked often. During high RPM running (highway) the Ninja 250 will pump oil from the crankcase breather into the airbox. Eventually the oil level will drop to an unsafe level. Once the oil light comes on it's too late. That tells you there is not adequate oil pressure. If it comes on when you are riding you need to pull over and shut it off immediately, and not restart it until there is adequate oil in the sump.
