one & the other

[John]

Are these all correct?

1. One of the twins is very feminine, but/and the other is a tomboy. ['But' is better, isn't it?]
2. One of the triplets is very feminine, but the others are tomboys.
3. One of her daughters is very feminine, and the other is a tomboy. [This tells us that she has two daughters, doesn't it?]

Thanks.

1. One of the twins is very feminine, but/and the other is a tomboy. ['But' is better, isn't it?] (If you want to make a contrast, "but" is better. If you just want to state the fact, "and" is fine).
2. One of the triplets is very feminine, but the others are tomboys. (OK).
3. One of her daughters is very feminine, and the other is a tomboy. [This tells us that she has two daughters, doesn't it?] (Yes).
