I’ve never watched these animes, but I’ll tell you what (I think) they’re about just from their cover art. If you saw any of these, let me know how far off I was. Told through haikus. Enjoy!
The God of High School
A young teenager
fights his powerful classmates
to get to the top
Kanojo, Okarishimasu
A classic harem
where a boy dates different girls
but has one waifu
Uzaki-chan wa Asobitai!
A playful woman
joins a normal family
and causes chaos
(Why do I have a feeling this is an ecchi anime?)
Kami no Tou (Tower of God)
A group of people
climbs a tower to defeat
the evil on top
(This one gives me major RPG vibes.)
Darwin’s Game
A group of people
have no choice to play a game
or else the world ends
(This one looks good. I might try it one day.)
evening tea musings 
God of High School (the only one I’ve watched more than one episode of): Those aren’t his classmates. I dunno why they call the tournament “god of high school”, but “god of society” sounds… kinda edgy and very narcisstic.
