Quintupled:

There is one by Philippe Leroy:
http://www.janko.at/Retros/Echecs/N444.htm

And there's one by, IIRC, Lois & Kapros, published about 2 years ago in 
Probleemblad, but it's not on the retros website, unfortunately.

The only sextupled pawn that I know of is a proofgame by Reto Aschwanden 
from the PCCC congress in Portoroz, but it used a fairy condition (ghost 
chess)
