darwin awards, page-2

Actually Priv_Joker, the Darwin Awards salute the improvement of the human genome by honoring those
who remove themselves from it in really stupid ways. This generally involves death of the person. However, the rules might have been relaxed a bit to include people who somehow render themselves incapable of reproduction (such as, actions that result in removal of their genetalia, and possibly something that puts them in a permanent coma might qualify).

So only number 1 in your list qualifies for a Darwin Award based on the reasonable assumption that the guy died. All the others do not qualify because the individuals are still alive and so can pass on their stupidity genes.
