Well, the four manga that were in front of Samurai 8 on the chopping block are gone. So, it still has protection to some amount (*) but its no longer safe if the new manga sells better than it.
* Kimetsu no Yaiba hit it big this year due to the anime but it was already nearing it end; so, it not going to last that long. Haikyu is ending. Dr.Stone should be ending soon and I don't know enough about its "reboot" to know if it is good or not. We Never Learn is ending soon. And I think Promise Never-land is nearing it end as well. So that's about five manga that may end sometime soon. Also One Piece apparently is reaching it end...in about 5-10 more years.
As for manga still on going or starting: My Hero Academy is going strong, One Piece is One Piece, Black Clover doesn't seem to be ending soon, Chainsaw Man seems to be popular, Act-Age is becoming a hit with an anime next year, Jujutsu Kaisen is apparently a hit, Yuna's Haunted Hot-springs is a harem manga so it will keep going till it stops, don't know much about Yozakura family or Mitama Security, Zip Man had an OK first two chapters, and A-Gravity Boys is... interesting? Though all the older manga are already more popular than S8; so, it is if the new ones can survive.
Zip Man is a story about two twins brothers. One twin, a genius, mind was put into a robot body that his strong but dumb brother pilots to fight evil robots to protect a girl they both have a crush on. The mangaka was a former assistant in MHA.
A-Gravity Boy is a story where in the near future humanity is extinct due to nuclear war except for four male astronauts that land on another planet. Then... some other dimensional entity gives them a elixir that will turn one into a woman. The three others quickly decided that they will be turning the scrawny already incredibly feminine medic into said woman. They fight, the medic threatens to destroy the elixir, they toss it, and depending how I am reading the ending either he just really is that feminine, was already a woman pretending to be a man to get into the program, or somehow was turned into a woman by the elixir without them knowing.
Edit: Sorry, I also forgot about HunterXHunter...whenever it even has a chapter.
