Q: 1. what does the control ring do? does it open and close the iris?

A: The ring on the KIPON Macro Lens Mount Adapter with Helicoid for Canon EF-Mount Lens to Canon RF-Mount Camera is not a control ring; instead, it is a helicoid ring that you may turn to elongate the lens adapter, thereby increasing your lens' minimum focus distance. When the ring is set to its standard position, you will be able to focus to infinity. However, upon turning the ring, you will lose infinity focus, but it will allow you to focus closer to your subject and increase its magnification.

Q: 8. Will this fit Nikon rangefinder lenses as well?

A: Whether related to patents, differing initial engineering decisions, or by mistake, the rangefinder coupling of the Nikon-S lens mount was slightly different than that of the Contax-RF.

The the Kipon adapter will work with your wider Nikon lenses but not anything above 50mm.
