How to store bagels?
I would keep the one that you are eating the next day out.  I would then freeze the rest of them.  

If you like them warm, you could freeze them wrapped in foil.  Before eating pop them in a toaster oven until gently warmed through.  

If not I'd freeze individually until solid then put in a bag to prevent your frozen bagels from sticking together, then thaw overnight (if eating in the morning) or in the morning (if eating for a mid-day meal) to eat.
