Is there a way to show the borders of multiple “objects” at once?

German Postalcode 06333
https://www.openstreetmap.org/relation/2409268

Region Mansfeld-Südhart
https://www.openstreetmap.org/relation/62681

Region Harz
https://www.openstreetmap.org/relation/62429

I need to see where they are overlapping.
