A few people asked if all 22 S-300/S-400 sites around Moscow are...

My TL;DR: Satellite imagery indicates that most air defense sites around Moscow remain intact, although some have lost a few launchers, while other sites are completely gone.

55.31037, 37.60879;
55.91933, 38.32886;
55.46814, 38.14255.
Some sites may use decoys to conceal removed equipment, but I find this unlikely. If decoys are used, they are probably deployed closer to the frontline.

There is also an issue surrounding availability of up-to-date sattelite imagery for some sites.

As others have noted, Russia's primary issue likely relates to deconflicting its airspace.
8/8
Each battalion is typically equipped with at least two batteries (or fire units), sometimes more.
Each battery has a minimum of 4 launchers, a fire and control radar, a search and acquisition radar, and supporting vehicles.
The search and acquisition radar can be shared by several batteries.
