If it were me, I'd count anything in the main Cairngorm range east and south of the A9, so from Glen Feshie in the west to Ben Avon/Beinn a Bhuird in the east, south of Aviemore, and north of Braemar/Glen Geldie. I think putting Ben Alder in the Cairngorms is a bit of a stretch, given it is well west of the Drummochter pass and well separated from the main Cairngorms by three passes and a significant distance, although I think one of my Munro books does include it, admittedly it has a similar profile to a Cairngorm mountain (big and bulky with a high plateau).
