Some updates for the charts:
TV season "banner", "fanart", and "poster" have been supported in Kodi core for some time before this PR. They are attached to each season with that exact name in the library, and the file names are prefixed with "season##-", "season-all-", or "season-specials-".
Artwork Downloader used "discart" in the Kodi library for skins, but saved the file as "disc.png". Ditto "clearlogo" as "logo.png" and I'm pretty sure "characterart" as "character.png".
For movie sets, Artwork Beef uses "fanart", "poster", "banner", "clearart", "clearlogo", "discart", and "landscape". The earliest support for movie set artwork that I know of is Movie Set Artwork Automator that supported all but the last two (and added "thumb", which may have been meant for the same usage as "landscape" for movies and TV shows). Like Artwork Downloader, though, it didn't require that the file name exactly match the art type in the library, so by default it used "logo.png" not "clearlogo.png".
I also really don't like referring to "landscape" images as thumb or thumb 16:9 - "landscape" is a primary image with a wide layout as opposed to the 'portrait' tall layout of "poster". "thumb" is short for 'thumbnail', and in the context of videos should be a still image from the video, possibly limited in dimensions. Artwork Downloader set up "extrathumbs" for movies like this, downloading and resizing backdrops from TheMovieDB. There is still some hardcoded behavior in Kodi core around the "thumb" image, and some skins and other interfaces still request a "thumb" image when they really want a poster, but "thumb" artwork is useful as a different image in the movie and music video libraries.
And for animated artwork, Skin Helper Service has been saving them to the video library as "animatedfanart" and "animatedposter" for skins to access. I prefer this strategy so that skins can use animated artwork for only the focused item, but the wiki's suggestion of swapping them for regular "poster" and "fanart" can also be used for skins that aren't specifically designed for it. The names are a smidge long, but "anifanart" is the only alternative I can think of and it sounds weird. I also kind of like the idea of animated logos and character art and maybe others, and prefixing existing art types with the same purpose with "animated" is straightforward enough ("animatedclearlogo" and "animatedcharacterart").

No limit as long as they are whitelisted. "fanart01" and "fanart1" are different (to pull these from the library without another add-on, skins currently have to specify each name exactly to display them), and zero padding in this case seems unnecessary even if there are more. I don't feel strongly about the zero padding as long as it is the same for everyone in all cases for all possibly-multiple art types, though.
File names still need to match the name as stored in the library to be picked up by these changes. If the whitelist configuration is later changed to include a count for each type then it might make sense for Kodi to normalize "fanart1" and "fanart01" to the same name to store in the library.
Edit: Movie set artwork is not currently supported in Kodi core, but MSAA and Artwork Beef support two strategies, described in the
first post of MSAA. I strongly suggest using a separate central directory; I dislike the nested folders so much I don't have it documented for Artwork Beef, though. As far as I know, there has never been a tool that would add movie set artwork to the Kodi library from files named as the Kodi wiki suggests.
