A g-iv flight crew suffered two consecutive conflicts with aircraft in the vicinity of their airport...

Narrative:

On descent into mvy we were setting up for what looked like a right downwind for runway 24. We were given a descent to 2;000 by ATC and told to make rapid descent because of traffic. As we approached 2;000 ATC issued a heading of 030 to get around the traffic. We had not been able to make visual contact with the other aircraft.while we were still in the turn we got a 'descend' RA. We complied with the RA and advised ATC what we were doing. As we received the clear of conflict message from TCAS the flying pilot began to roll wings level. At this point; the non-flying PIC made visual contact with the aircraft. It appeared to be a single engine. [However; as] the flying pilot rolled wings level a second aircraft was in our front wind screen. The flying pilot took evasive action by descending and turning left.the second aircraft was a twin engine piston aircraft; perhaps a cessna 402 that looked to be headed for mvy. As the flying pilot was taking action the TCAS gave RA call outs with which we complied. We were approximately 500 ft from the second aircraft at the same altitude. After this we told ATC about the second aircraft and [then] went on to land on runway 24.

Title: A G-IV flight crew suffered two consecutive conflicts with aircraft in the vicinity of their airport of intended landing. They followed a TCAS RA to avoid the first then came nose to nose with the second from which they took undirected evasive measures.
