ᐅ Cracks in the facade 7 years after painting

Hello,
We bought our house, built in 1970, seven years ago.
It was repainted when we purchased it.
I have noticed the following cracks.
Is it okay to leave them as they are? They don’t bother me. Or do they definitely need to be repaired?
If so, how should this be done?

In the second-to-last picture, where a stone is protruding, is there no ring beam? How far does the window lintel extend, and is there a roof beam resting directly on the stone?
The other cracks are cosmetic.

Is there no need to worry about the thermal insulation system beneath it in the first picture, like water getting in or something? The crack is probably too narrow for anything to happen there? Here is a closer picture.

Is this a prefabricated house? I find it difficult to explain the vertical cracks.

It dates from 1970, I believe it is built stone on stone. What could that be?

What comes to mind: a few weeks ago, we had a new roof installed. There was quite a lot of noise, and at times it sounded like bangs throughout the entire house, you would have thought they were about to break through the ceiling. Can such vibrations cause something like this?
However, I'm not sure if it was already like this before.
