I think the reason Raven wasn't affected is because the second time Ruby used her SE powers, it was weaker and to a lesser extent than before. Ruby only reacted to a flashback of Pyrrha's death rather than the actual event so the SE powers weren't as powerful as the first time. Only Cinder was affected because either

A) Cinder might have been physically closer to Ruby than Raven, and the SE powers didn't expand to Raven before Ruby was knocked out by Emerald.

or

B) It wasn't strong enough to penetrate through and damage the Maidens but it did affect Cinder's exposed Grimm arm.
