A pale-pinkish tinged, white hairy gall of Cynips multipunctatus is at center, with a greenish one seen to the right. I think the red "rocket" at left-of-center is a single, naked, early stage of an Andricus crystallinus gall...looking different than the perhaps more familiar form which typically occurs in clumps of many such "rockets" obscured by a dense, glistening thatch of long-ish, somewhat wavy hairs (perhaps appearing as the galls mature, though that's just my speculation). The blurry red at left (center and bottom) are more typical A. crystallinus.

These galls are on the same blue oak (Quercus douglasii) seen in the post below:
