Can 8 speed dura-ace downtube shifter work with 9 and 10 speed dura ace rear derailleurs in friction mode? Has anyone tried it?

Yes, but 10 speed cog spacing is so close it would take a real light touch.

Yes. It will also work for 9-speed indexed shifting with any Shimano rear derailer except the pre-9-speed DA. The last shift won't have a "click", though.
