I think technically the Agents of S.H.I.E.L.D., Agent Carter, Inhumans, Runaways, and Cloak & Dagger are technically supposed to be part of The Sacred Timeline, but I'll admit they don't always line up 100% with the movies.
The first 2 or 3 Season of AOS fit pretty well into The Sacred Timeline, but as the show goes on it gets a bit harder to fit in as the show goes on.
I still think it's feasible for season 6 to take place in the post-Snap world, since we don't really see that much of the larger world beyond the team, and the various recurring characters who don't appear in that season could be presumed to have been Snapped. I figure that a year after the Snap, people are still in denial and trying to go on with their lives as if it didn't happen, as opposed to the deeper despair that's set in by
Endgame. It's conceivable that the main cast could've avoided Blippification, by the same token that the
Iron Man cast and core Avengers all survived while other casts like
Ant-Man, Black Panther, and
Spider-Man were completely Blipped. Just because it was 50% of the whole population doesn't require it to be exactly 50% of each individual small group, because that's not how randomness works.
Although I'm open to the alternative that the team being taken to the future at the end of season 4 created a new timeline that they were in through seasons 5-6. Arguably that's obligatory by
Endgame temporal theory. I'd like to think that at least the first four seasons are in 616, since the early seasons meshed so closely with the movies. The problem is that there's no sign in the main MCU of all the world-changing Inhuman stuff that happened in AoS. But one could handwave that maybe the Inhumans ended up moving to Attilan on the Moon during the Blip years.
I don't think there's anything that really prevents Inhuman, or Runaways from fitting into the Sacred Timeline, but there's also nothing that solidly places them in it. I haven't seen Cloak & Dagger, so I'm not sure where that one stands.
Runaways season 3 contradicts the time travel physics established in
Endgame, but then, so do the X-Men movies that have now been folded into the MCU multiverse, and arguably so did the climax of
Doctor Strange. C&D, as far as I recall, has no issues. It references
Luke Cage and crosses over with
Runaways, and it features the Roxxon Corporation, which was frequently featured in other MCU shows and films.
As for the Hulu shows I only watched one episode of M.O.D.O.K. but one is definitely not part of the Sacred Timeline. I haven't seen any of Hellstrom or Hit Monkey, so I don't know how they'd fit.
Helstrom (they changed the spelling) was originally conceived as an MCU series, but by the time it aired, they'd decided to treat it as its own unconnected thing. The animated shows are not meant to be part of the MCU.
