The problem in your hands demonstrated is that you don't seem to understand the rules of Omaha. The rules state you must use EXACTLY 2 cards from your hand and EXACTLY 3 cards from the community.
In hand 1, the two cards you would use from your hand are clearly the 2 aces, on the community you would use the 1 ace to form trip aces. However no other community cards are paired, so you cannot make your full house. Your hand is AA from your hand, and AKQ from the community, making your hand Three of a pair Aces, with King and Queen kicker.
In hand two, you do not have a flush because you are trying to use three from your hand and two from the board. Only cards in your hand that pairs to make anything is a 7, and a 4, so you would use those two with the 7 and 4 on the board to make two pair, King kicker.
Hope this helps,
