ManyA group of people play games to win an enormous amount of money in the story.

"Many" implies that people in the general public do it.

At first, there were 450 participants, and 250 participants were illueliminated in the first game which was "green light red light".

Not sure if this should be a correct; the game seems to be based on a game kids play. I always called it "red light green light." But the order probably doesn't matter here.

When they were illuminated, theyeliminated, the participants got shot, but their blood looked black on the screen.

"On screen" is a common phrase that doesn't need a/the.

A slight rephrasing.

The games (that) they play require strategy and alliance(s).

"Game" is part of the title so needs to be capitalized

At first, there were 450 participants, and/but then 250 participants were illuminated in the first game which was "green light red light".

A changed to B so "then" helps the reader/listener understand your meaning. "It was a sunny day, and/but then it rained." or "I was bored, and/but then my brother came over." are similar examples.

When they were illuminated, they got shot, but their blood looked black on the screen.

a "season" is singular so "has" not "have"

They discus abouts the strategy well, but sometimes, some people hide their agendas.

"talk about" "think about" are phrasal verbs requiring a preposition to function. They typically have a Germanic origin. "discuss" or "consider" are Latin origin words in English and are rarely used to make phrasal verbs. I think it's similar to Chinese origin verbs in Japanese that use する.

"Game" as a part of the title also gets the capitalization.

Without the "the" in the sentence, it sounds to me like a general thing, like they could be playing Pokemon Go or Fortnite. "The" helps communicate we're talking about "The" Squid Games.

At first, there were 450 participants, and 250 participants were illueliminated in the first game which was, "greend light greden light".

The comma at the end is required either way, but removing "which was" I felt just makes it flow a bit better. "The first game, which was 'green light red light.' would also be fine, I think.

I just checked and the blood looks a sickeningly realistic dark red to me. I wonder, especially with your "season 2" comment in the next sentence, if you might not be talking about the show, "Squid Game: The Challenge," which is just a reality TV show based off the original. You could maybe call it a "spin-off."

If that's not the case, though, I'm a little confused by "season 2," but now that I'm looking for it I do see that there are some trailers for a season 2 to release sometime next year? Not sure what to make of it yet.

They discus about(often) discuss their strategy well(thoroughly), but sometimes, some people hide their agendas.

We "talk about our ideas", using "about" because talking refers not to they conveyance of these ideas, but the speaking of words. Thus we use "about" to mark "our ideas" as an indirect object. We "discuss our ideas" because "discuss" refers to... well, I like the word you used in the Japanese version to explain it, 話し合う.

well -> often or thoroughly: The よく in the Japanese version matches Englishe's "well" in most cases but it just feels a little unnatural here. It's also a little ambiguous. Please correct me if I'm wrong, but I believe the よく in the Japanese version can be interpreted as "sufficiently/十分," "skillfully/うまく," or "frequently/regularly/たびたびに," or perhaps a mix of all. Tied with 時々 I'm inclined to assume "frequently"? In the English version, "well" can have all those meanings, but the feeling I get from this "well" is "skillfully," but it feels a little unnatural here. So I would suggest using either "often" or "thoroughly".
