'Flight crew' generally refers to pilots, engineers, etc. That number for the A380 is two. Extended tours of duty would require supplementary crew. For typical LAX flights that will be 4 crew in total- 1 Captain, 1 F/O, 2 S/Os. In the short term though, many flights are over crewed. A flight last night had three captains, one F/O and one S/O. Training requirements or something like that.
If by 'flight crew' you meant 'air crew' which means both cabin crew and tech crew then I seem to recall the 744 having 15 cabin crew. I have no idea how many cabin crew on the Dugong.
