The balcony should not be paved with wall tiles

If the brick laying has no effect, it will be better if it is paved.

I don't think you need to pave it, it's weird to pave it, of course, it will be better to clean the wall tiles, but you are sure that it will be cleaned for a long time in the future.

It doesn't have much of an impact, it is recommended to tile the part under the windowsill, and the working part is not necessary.

It mainly depends on what style you decorate, etc. It depends on what you like. Whether your balcony is open-air or indoor, my suggestion is to lay wall tiles on the open-air balcony and paint the exterior wall indoors.

It mainly depends on your decoration style. The open-air balcony is paved with wall tiles, and the interior is painted on the exterior wall.

The wall tiles are easy to rub, but children may fall and hit them when they play.

Painting exterior walls or laying wall tiles is fine.
