from your description you are either a very lucky LUCKY son of a gun, or you just spotted drones.
if you are indeed very lucky, i don't actually know what you should do, but if they haven't swarmed they superceded, still if it's true what you say-multiple queens, you could make 3 hives out of one, if you had the means neccesary to do this, but since you're a newbee i doubt you have enough boxes and built comb.
