Who are the main characters in the Squid Game story?

Fang Heng was transmigrated to a parallel world and his soul was forced into the body of a man who had just committed suicide. Huh? What? Every human here was being forced to join a game? Those who refused would be killed? Wait? This suicide dude was a pro gamer? He had the highest S-rank talent sill, the Zombie Clone? Damn! The S-rank skill evolved! My zombie clones could auto hunt! [Your zombie army has crafted Wooden Axe x720 when you were offline. You have received 1921 experience points for the Basic Crafting skill.] [Your zombie army has chopped down 27,821 trees and gathered 128,973 pieces of wood while you were offline. You have received 2,171,921 experience points for the Basic Wood Chopping skill.] Just as the rest of the players were struggling to survive in the zombie apocalyptic game, Fang Heng's zombie clones were starting to clear every resource out of the forest. Hm... What an interesting game!

Bell Cranel was rejected by every familia he tried to join until he met Hestia. In a few, he was rejected quite violently. And in one particular instance, he was thrown out and bashed his head against a wall. Well, that's apparently where I come in. Not sure how and why I'm here. Not even sure who 'I' really am at this point since Bell's memories are definitely clearer than 'mine'... But I guess we're doing this. Hopefully I've got some useful cheats. Maybe?

Tell me, what would happen if a regular man reincarnated and spent his young life in the Marvel Universe to only find that upon reaching 20 Years Old, he would get his Gold Finger?

Lu Wu, an aimless video game developer, had been feeling perturbed ever since he found out he was the direct descendant of a king from the underworld. Other than the title, His Excellency, his ancestor hadn't passed down anything else to him. On top of that, all of his ancestor’s subordinates had rebelled against him and completely usurped his inherited territory. Under the circumstances, Lu Wu built a battle game server with the help of his new mysterious friend and transported gamers from the real world straight to the underworld using virtual reality. They then created the main quest, the character classes, the Instance Dungeon, the storyline, and the non-player characters for the game. Relying solely on these video gamers’ strengths, Lu Wu began his expedition to reclaim his rightful inheritance. What could possibly go wrong?

An alternate realm invaded and the game descended. The entire Blue Planet was digitized. Faced against countless waves of monsters, some people downloaded the Holy Knight module and became angels of light that helped the world reach enlightenment. Some people downloaded the Warrior Monk module. They focused on their training and reached enlightenment overnight. With their fists and legs, they fought and made a name for themselves. Chen Kun, who transmigrated to this world, downloaded the Boss module. Each time he leveled up, his growth attribute improved multiple fold, and his attribute points multiplied. More importantly, all his skills were automatically unlocked as boss skills! When the hole between the two realms opened and the gods of the alternate world came pouring in to invade this world, what awaited them was Chen Kun, who sat high up on a throne. When the gods of the alternate world saw his terrifyingly long health bar as well as his boss skills that granted instant death and control immunity, reduced damage, true vision and many more skills, they despaired. Chen Kun smiled and said, “So, are you the ones who will challenge my throne?”

Razel, is a reincarnated youth. In his previous life he was a lonely boy who spent his days playing video games. Then one day tragedy came into his life. It all ended for him, was what he thought, until he opened his eyes; to find a fantasy world, where science and magic go hand in hand. That could have been a joy, but that happiness was nipped in the bud, because he reincarnated as the eldest son of a poor family of barons without territory, and, above all, he is uglier than in his previous life. His tragic new life doesn't end there, as he woke up in the last video game he played. An otome game. But not just any otome game, it is one with an RPG theme so it is made up of strong and dangerous enemies. He will have to live his new life as a background character and help from the shadows to the capture objectives and the protagonist to avoid the end of the world and especially, the cruel villainess.
