I've had six in my current playthrough that I remember off the top of my head, or at least recognised as randoms whether via prior knowledge or researching after the fact. Two beggars (though one I reloaded and it didn't appear again), a merchant, some rogue plasma walkers, a guy half dead needing aid and several dead gangsters around a bag.
Funnily enough I thought the guy being half dead was related to the dead gangsters. He had killed someone, survived, I fixed him up and he lived to see another day. Later coming back, there was the bag and three dead gangsters on the same spot as the previous dead guy, wherein I presumed the one I aided had finished the job properly this time round, to later find they were separate random events and they just over-lapped on each other.
