Which is your car, the red one or the blue one?
My trousers are torn. I need some new ones.

See those two girls? Helen is the one on the left.
Let's look at the photographs – the ones you took in Paris.
after which in questions:
You can borrow a book. Which one do you want?
Which ones are yours?

- one and ones 2

Hello Jude
Both sentences are grammatically correct but mean different things. What is the idea that you want to express here? The first one would suggest a score of 1 on a scale of numbers, for example 1 to 10. The second suggests he is the one chosen to do or be something.

Hello Rhyna,
We would not say 'two ones'. We would most likely say just 'two', but 'two of them' is also possible.

Hello Rhyna,
Yes, you are right. Both parts should be phrased as questions:
Can I use... or should I use... ?
Well done!

Hello Abfalter Cristian,
In English, adjectives are not used to substitute nouns in the way they are in some other languages. I don't know Romanian, but in Spanish, for example, using an adjective in this way is common.
So in the first sentence, the best thing is to use 'one' in both gaps. You might be able to find examples where this rule is not followed, but in general I would not recommend it.
All the best,

Hello Lijo John,
'One' is counted as an indefinite pronoun, yes. The relevant wikipedia page has a useful table:

Hello FirasAkkad,
That was a mistake! It should end in a question mark and I've now fixed it.
Thanks very much for taking the time to point this out to us.
All the best,
