What are the meanings of these epitaphs?

i only know a few... i think.... haha! the 2nd one means that "the guy" didnt have a very good rep, it was ruined and couldnt be completely fixed. the 5th one means that just because your a gentleman that doesnt mean you are everything. the 6th one is that water isnt worth much, haha! (theres probably a deeper meaning but lets not go there!) and all the others, espacially the last one, i do not know... terribly sorry... why do you want to know this anyway??? heehee!!!!
