We can use one instead of repeating a singular countable noun and ones instead of repeating a plural noun when it is clear from the context what we are talking about.
e.g.: Can I get you a drink? It's okay, I have already got one.
I think his best poems are his early ones.
We don't use one/ones instead of an uncountable noun. We can't use ones without defining precisely which group of things we are talking about. Instead, we use some.
e.g.: If you need any more paper, I will bring you some.
We need new curtains. Okay, let's buy some.
We don't use one/ones after nouns used as adjectives.
e.g.: I thought my key was in my trouser pocket, but it was in my coat pocket.
We usually use ones to refer to things rather than people. However, ones is more likely to be used in comparative sentences to refer to groups of people.
e.g.: Older students seem to work harder than younger ones.
