All of these are gases to which you could be exposed in a laboratory (if you were careless and unlucky). Of course, there are any number of war gases that were designed to irritate and to kill, and were widely employed in the Great War. Probably the worst ones employed were the mustard gases; their effects even appalled those who employed it.
