Answer 1

the cool, refreshing breeze drifted across the deep, still waters of the sea.

the crisp, sunny day beckoned; and keith marched off to meet his friends. (if not right please correct)

Answer 2

Ok, look at the thoery behind this. The commas go between the adjectives (something that describes) like crisp, sunny or cool, refreshing. They also go where you want to separate two ideas COMMA but they are linked enough to not use a full stop.

Once you get the idea COMMA it becomes quite simple.
