No BVR missiles yet. This will be the METEOR missile, during 2005 the Gripen will perform live fire tests of this new European missile.
It can hold 4 of them. (plus 2 sidewinder or IRIS-T also new European missile.)
I have never seen any info on how many targets it can track at once. it is however multimode, can work passive, and of course with the datalink,
radar nfo can be fed from other jets/awacs or ground stations without giving away the position of the engaging jet/missile.
