At least the 3rd photo is Hamburg … elbphilharmonie at DuckDuckGo … the rest would fit Hamburg, too, and some labels here and there give it away.
The church is in Hanover (thanks, Google picture search).
Foreword: I don’t really know what I’m doing when it comes to photography, I just point the phone at something, touch the spot on the screen that I think is most important for that scene and hit the shutter button. So my examples are basically the bare minimum you can expect when not putting any effort into the quality of the result.
Cloudy autumn day in Hamburg, no editing, just the defaults
