Which ones are grammatical? Can we use Sentence 1, which means Sentence 2 or Sentence 3?

2 is correct. The others are wrong.

Sentence 2 is grammatically correct and conveys a clear meaning. The use of "some" and "others" accurately distinguishes between the different colors of the balls.

Sentence 1 is not grammatically correct because it includes the phrase "the other is green," which implies there is only one other ball. However, the preceding sentence mentions multiple green balls, so it contradicts itself.

Sentence 3 is also not grammatically correct because it includes the phrase "and the others are blue." The word "others" should only be used once to refer to a different group, whereas in this case, it is used twice without a clear distinction between them.

When referring to a collection of balls with different colors, it is best to use Sentence 2 to avoid confusion and ensure grammatical accuracy.
