I only know these two, they're GL btw:
https://www.mangago.zone/read-manga/genjitsu_sekai_real_demo_shiawase_ni_shite_kudasai_ne/ (multiple FLs transmigrated from a video game into the real world to be with the MC)
https://www.mangago.zone/read-manga/the_fresh_start_of_elegant_beauty/ (FL transmigrated from the Tang dynasty into the modern era)
(I have no idea if this actually exists)
- main character actually is from the world and other characters are the transmigrated individuals
