Number of roof windows and positioning of the windows

Yes, we are doing that in parallel. Hence the question about the quantities of roof windows.

You’re not serious now, repeating your initial question???
We can also start again at post 2 o_O
As I already said: your floor area needs light. And if not roof windows (for whatever reason), then through gable windows or a central window position. You need to get your brain going yourself now. I would have expected your own placement and correction here long ago.

Where is north?

I can only agree with . Currently, the windows are distributed evenly. You once wrote somewhere that one is probably opposite the stair ascent.

So, approach it, check where which areas in the room could be and where windows would be nice. And regarding photovoltaics... where is north now?

If photovoltaic is planned, then better 2 large skylights than 6 small ones. Or at least not spread out over the entire area like that. Where is north? Then better place the skylights there.

... where is north now?

I can only agree with that.

Sorry guys for the late reply. Norden is at the top of the plan.

This is how I would plan it, unless the usage requires something different.

For photovoltaics, a maximum of 2 * 21 modules can be used. 42 * 440 watts = 16.8 kWp. Which unfortunately is not optimally utilized with E/W orientation.
