Well, I was going to guess the flags meant different types of fish caught. For serious answers, just what I can see (some are impossible to see due to shadows and folds),
1. USS Midway.
2. Red and yellow diagonal, man overboard. The white and blue appears to be the signal that the ship has a diver below the surface, approach with caution. Half white, half red means I have a pilot on board. white with red X indicates I need assistance. white with red diamond indicates I am disabled, communicate with me. The other red and yellow might indicate I'm dragging anchor...can't see if it's striped. Blue over red indicates I'm steering towards starboard, course change. Can't read the other whie and red, could indicate approaching danger.
And of course, the red white and blue...thirteen stripes signifying the original colonies, 50 stars indicating present day 50 states.
