I wouldn't really do much to these!
Cropping would mean you'd need to take out the third person in the background. Which no longer works as easily for the second photo as it would for the first - though taking a second look at the first suggests that cropping him out would already clip into the falling person's fingers. No, actually, I'd leave these as they are.
The first photo looks great the way it is. It shows the action,and some context for the action. One could, I suppose, crop off a small amount of the left hand side of the top photo, eliminating the two people in the upper left hand corner.
