I like how the 1st turned out, capturing those shadow/rays.
For the others, it's always a trade off between sun expsoure and the surroundings. I like to play with auto white balance on these first, then manual WB tweaking (as well as exposure) to see how such might be presented differently (not sure if that yellow cast was the cast of the moment, or from in camera WB setting).
If you're not shooting RAW, for such extreme DR shots it's worth while to at least attempt to capture one in RAW, for more latitude in making corrections. Also, bracketing exposures (manually or automatically) can be helpful.
For ones such as the first, a Neutral Density Gradient (NDG) filter can help to tame the sky brightness, in order to be able to capture more of the foreground detail (where the FG is not forced into deep shadow).

You'll have to ignore the gallery's collection of bad compositions, improper exposures, and amateurish post processing.
