Can lintels on balconies be fitted with rings?

Yes, find someone who makes curtains, they will get it.

This should be considered from the perspective of security and privacy, and there are other people walking around under the balcony, and it is also troublesome if the water leaks, so I don't think it is very suitable.

Beekeeping is available on balconies and rooftops, but it is important to shade the colony in high temperatures, but be aware of safety.

It mainly depends on your needs, if the balcony is closed, especially in summer, you can install a curtain to block the sun, and in addition, you can look at the harbor house if the curtain is closed

The balcony wall is not allowed from the overall point of view, because the balcony itself is protruding, and there is no support under it, that is, its base is relatively weak, if the wall is built, we are afraid that it may not be able to support, and finally cause unnecessary trouble. But people always have a lot of ideas, and it doesn't mean that the balcony must not be built with walls, as long as we follow some rules and pay attention to it, it is still okay.
