If you are speaking of occupying a place in the manner of a physical body, angels are not in ANY place.
If you are speaking analogically, saying that an angel is "in" a place when he is acting in some manner in that place, then there is no limit to how many places that could be.
I showed scripture that shows they can only be in one place at a time. If you disagree show the passages that indicate they can be in multiple places.
