Yes, they're completely hot-swappable.

Think of them the same way as cables (note the link lights). Same for SFP+ direct-attach cables. It wouldn't make sense for them not to be hot-swappable. Heck, most network switches don't even have power switches :)

Generally yes they are, certainly I've never come across any that weren't - in particular I know for a fact that the top three on your list are, not used the bottom one so can't say with the same degree of confidence.
