As someone who has only seen agadmator's videos.. And no clue about other famous people, can someone tell who are the people in the picture, other than Magnus and Anya Taylor Joy?
Bottom right is Levy aka Gotham Chess on YouTube. Top right is another famous YouTuber, I forget her name but she recently won chess streamer of the year (maybe last year).
As the other response said: top right are the botez sisters, bottom right levy rozman a.k.a. gothamchess, bottom left is tyler1, a famous streamer from the league of legends scene who started playing a lot of chess. Interspersed around the licture are also small hikaru's whom you probably do know if you watch agadmator
I'm a big fan of Magnus. Dude is overall a good role model, respectful and serious most of the time, while also being meme-ey, approachable and fun. Unique playstyle to boot.
He's actually largely responsible for me personally starting to pay attention to the game again. I hadn't even played in years.
