1, 2, and 3 are very much the same. In addition, #1 conveys the idea that he died too young. That is, he was a young man who shouldn't have died, but he did.

Yes, 4 is the opposite of 5. And, yes, all the expressions in 6 and 7 are just fine, depending on the exact meaning. A north wind, for example, means wind coming out of the north, and so forth.
