Just to confirm
EF "L" lenes ok on a Rebel
EF S lenses not ok on a 5D

Friend has a Rebel and I want to loan her my L glass to use on it. OK?

You are correct.

In addition, just so there's no confusion - there is NO DIFFERENCE in how the marked focal lengths "work" on an APS-C format camera. In other words, an EF 50mm lens and an EF-S lens set to 50mm will provide the same field (angle) of view on an APS-C format camera such as the Rebel.
