I'm glad you asked, because I was afraid my wording was unclear.
One time use exemptions. You could in theory save them all the way to the final battle with Cynthia if you desired.
For example, if you wanted to use Chimchar against Gardenia, or you wanted Chimchar to use Grass Knot on Crasher Wake's Quagsire, it would consume one of your exemptions for Chimchar, and it would last that Gym battle for the entire battle (after Chimchar uses Grass Knot on Quagsire, he can continue to use Grass Knot on Wake's remaining Pokemon if desired). However if Chimchar is KO'd, it will cost another exemption to use that Pokemon again in the same battle.
