Mapillary might be a useful resource; it’ll show you the inside of (some) U-Bahn stops, which Google won’t: https://www.mapillary.com/map/im/p05PTPfTnxCOxR7lB9KpNP
This pic shows that Hönow (last stop of U5 East) is out: U5 runs above ground there.
I seem to remember brown walls in a number of U5 stops between Alex and Frankfurter Allee.
Why do you need to know, if I may ask? Sounds like a detective story.
Edit: in early 2014, Boddinstraße was the last stop of U8 in Neukölln, see https://www.tagesspiegel.de/berlin/bauarbeiten-bei-der-bvg-in-berlin-u-bahn-linie-8-bis-2014-unterbrochen/8622058.html
Cars don’t park there at an angle, though. https://www.mapillary.com/map/im/AJMjsOAAXFs8jGG4nJ4AkO
Edit2: Wikipedia has pictures of U-Bahn stations, see articles linked from https://en.wikipedia.org/wiki/U8_(Berlin_U-Bahn) (same for U2 and U5). They have pretty distinctive colors, so this may be your best bet. I’m retracting what I said earlier about brown stops at U5. I do have Pankstr and Rathaus Reinickendorf on offer, though: https://en.wikipedia.org/wiki/Pankstra%C3%9Fe_(Berlin_U-Bahn) https://en.wikipedia.org/wiki/Rathaus_Reinickendorf_(Berlin_U-Bahn) Both are close to the North end of U8.
