I am quite a beginner in respect to GIS and hopefully someone can help me out with the problem I have.
I have multiple digital surface models [DSMs] of the same area with all necessary geo-information (6 in total). However they are not exactly the same as they have been acquired on different days (row and cols of the raster are not identical). I already managed to align the DSMs, however now I need to find the intersecting area that is part of all six DSMs because I want to do some processing with this (which I indent to do in python). I found the following post:

This methods works fine for two DSMs, however the extension to more areas is not straightforward (at least not for me at the moment).
I guess this is a rather standard beginner problem, however I only ever found answers regarding exactly two areas.
