From my understanding:
if a player is 44/4, it means his VPIP is 44, and his PFR is 4
These are expressed in percentages.
ie: the 4 means he preflop raises 4% of this hands
An ideal stat that a majority of regulars maintain is 18/12
Meaning 18% hands that you are dealt are played, and 12% of total hands dealt are raised pf
I'm not sure if this varies when specifically facing a LAG, but that is an excellent question that i'll be interested in hearing responses to.
