The only one of those I'm not sure on is the expose one. The rest seem like they already exist in emacs.
It is probably mentioned in every editor thread, but org-mode is enough magic with an editor to mystify most developers. Syntax highlighting for multiple languages in a single file is already stretching most boundaries.
What's the point of the graphics in git-time-machine? The bubble plot seems less useful to me than a readable log. If it were useful there would probably be an equivalent findable from https://www.emacswiki.org/emacs/Magit
The question isn't "do I like these extensions?" It's "does Emacs let you build these extensions?" The Atom developers thought that providing this flexibility was important, which is at least in part why they used the technology they did.
I don't know on the actual charts, as I just don't use that sort of thing. Seeing anything git related and I think magit. Pretty much period. That is, I didn't see the chart.
You can do graphics in emacs, though. I typically just use it to show email and inline images for org-mode.
