Answer 2

1 and 2 -- mean the same.

3 and 4 -- mean the same.

5 is OK if you ad "your" before "health."

6 is not used.

7 and 7-1 mean about the same thing, but better phrasing would be this:
<i>Some are rich, but others are not.</i>

8 is very awkward.
8-1 is better, but would be best this way: <i>One is happy, but the other is not.</i>

Again, 9 is awkward.
Best phrasing would be this:
<i>Some people are healthy, but others are not.</i>

Answer 3

5 is OK if you add "your" before "health."
