In your list I would use these terms: 5 is last 4 is next to last 3 is second to last 2 is forth to last (more commonly "second"!) 1 is first (fifth to last is getting to be a bit of a stretch) So you have the LAST one. The one NEXT TO it (which is ONE away from the last one). The SECOND to last counts two away from the last one. More @Wikipedia
