Yes! You can say 'the tall one' to refer to a person if it's clear you are talking about people. Example: 'Which boy is your son?' 'The tall one.'
In formal writing, it's better to just say 'these'. However, in daily conversation, 'these ones' and 'those ones' are very common and perfectly acceptable.
In standard English, we use possessive pronouns like `mine`, `yours`, or `his` instead of `my one`. However, if there is an adjective, you can use it: `my new one` is correct.
No. 'One' and 'ones' are only for countable nouns. For uncountable nouns like water, just repeat the noun or use 'some'.
`It` refers to a specific, unique object. `One` refers to a type of object or one choice among many.
Not always. You can use it after 'the', 'this', 'that', or 'which'. Example: 'I'll take the one on the left.'
Using 'one' to avoid repetition is neutral. Using 'one' to mean 'a person' (e.g., 'One must eat') is very formal.
Usually, we say 'a [adjective] one'. We rarely say 'a one' alone unless it's the number.
