We had two opposite direction GA aircraft with assigned altitudes only 500 feet different than ours. We were level at 6000 feet. GA aircraft crept toward us vertically. We received multiple RAs (resolution advisories). Closest point was zero separation laterally and 300 feet vertically. Incidentally; these aircraft also triggered an RA with the aircraft in front of us as reported on the frequency.
B737NG First Officer reported an near mid-air collision with a light aircraft in the vicinity of RBV at 6000 feet.
