Yes I understand both lights on at the same time but if the PIRs are
set for different duration times will it be the activated one that
decides how long they stay on for?

It will be the end of the last one activated, whichever finishes last.

I have it sorted now but to clarify its like an alley at the side of the
house the PIRs are either both activated or just one depending on
circumstances, it is wired so that both lights come on regardless of one
or both PIRs being activated.

It was set up a few years back but for some reason the settings unsetted
themselves when they came on they would stay on for say 2 minutes turn
off then straight back on again, the problem was in the PIR settings not
the LED lamps. (and I lost the instructions), maybe due to the hot
weather or some other reason so I had to bring them back to a useable
sequence.
