I'm pretty sure the second one is LTV's Crossbow launcher. It was a competitor to Avenger and was offered with a wide range of alternative armament (Starstreak, RBS-70, Stinger, Hellfire, Hydra-70 rockets, and either a 25mm cannon or .50-caliber machinegun).
Edit: In fact, looking at that picture, I believe it's showing a version of Crossbow with Startstreak in the two side pods).
