We encountered 2 RA events on a Part 91 reposition/ferry leg to LGB. The pilot flying was receiving type specific instruction.IFR route clearance was: Fly runway heading; radar vectors; maintain 3000 feet. After level off on assigned altitude of 3000 feet ATC advised us of VFR traffic at 3500 feet at our 11 o'clock. We saw the traffic and I reported the traffic in sight. As we crossed under the single-engine piston airplane we received an RA: 'Do not climb.' We complied.Shortly thereafter ATC instructed us to descend to 1600 feet. As we approached 2000 feet ATC instructed us to level off at 2000 feet and advised us of another traffic at 1500 feet at our 10 to 11 o'clock. As we leveled off I sighted a helicopter at our 11 o'clock position moving from left to right in level flight 500 feet below us. I reported the traffic in sight and told ATC it's a helicopter. We then received an RA to 'climb; climb.' My copilot maintained level flight. By this time we were crossing above the helicopter and I had the traffic in sight. I determined there was no traffic conflict so did not take over the controls and allowed my co-pilot to continue flying. The flight concluded with an ILS runway 30 approach to LGB in visual conditions. During the post flight debrief I clarified to the co-pilot the importance of complying with an RA. He did not know that a TA/RA event takes precedence over ATC instructions. He was also unaware to the requirement to comply with an RA. I will bring this matter to the attention of the training department so these misunderstandings are corrected as soon as possible.
An Air Taxi Captain reported encountering two conflicting aircraft. The first TCAS warning indicated 'DO NOT CLIMB' and a second aircraft warning 'CLIMB'; which the First Officer did not follow.
