Second picture is Mokoli'i island probably seen from some beach along the Kaneohe Bay or possibly from the Kualoa beach park area.
I think the mountains in the back ground of the next three pictures are the Koolau Range.
The coral was seen along the same beach in front of the mountains.
I am not sure where the kite-sail boarders were.
The last two pictures were from close to the north tip of the windward coast.
