maybe i am doing something wrong but as far as i can see all the lights are not in touch with geometry.

Adding to that problem is the fact that I believe arealights probably use a differerent and more efficient light sampling that mesh lights.
In fact, in your first examples, those crazy bright paths in secondary bounces are able to get into primary rays as well.
For instance in this example I have to use a very contundent sampling strategy, with as many as 1024 FG samples, to get rid of very bright high-contrast FG samples on geometry close to light sources
1024 FG samples x 3 AA samples
