Will brambleclaw ever have kits with squrrielfight from the warrior cats books?

No, SqurrielFlight and BrambleClaw never has kits, but SqurrielFlight takes care of her sister, LeafPool's, Kits; HollyKit, LionKit, and JayKit, Because LeafPool was a medicine cat when she had her kits in the forest with CrowFeather of WindClan.
