Whose priority?

I saw a question about KET, I think it’s time to ask about two situations where I’m not entirely sure how to act.

The first situation. The main road intersects with the side road. The red one on the main one turns around, and the blue one on the side one turns right. In this situation, it seems clear that blue should miss? although in reality he sometimes misses the main driver.

The second situation is more complicated, because both lights are green. It would seem that the right-hand rule should apply here, and the one who turns around and there is an obstacle from the right should pass, that is, the blue car should give way?

How is it really? Do we have KET experts here?
