Which one is correct?
She is younger than me.
Or
She is younger to me.
My teacher said, some adjectives like ' senior, junior, superior, inferior, major, minor, interior, posterior, younger, elder, prefer' are not followed by 'than' instead 'to'.
So, are these adjectives correct to be used with 'to'?

Simon is correct about "younger than"; this may be because "younger" is a comparative adjective, similar to his example of "hotter", and many others. In the case of "elder", it has largely been replaced in comparative adjectival use by "older", so we would say "older than him" rather than "elder than him".
Your teacher was partially correct about the other words. They are not comparative adjectives and are not followed by "than" unless in comparative constructions using "more", such as "He was more senior than Jane". Note that this means he was in a more senior role (but not necessarily responsible for Jane; he might even be in a different company) than Jane, whereas "he was senior to Jane" usually implies that he was in a more senior role but also was directly responsible for her.
I make no comment about "prefer", which is the only verb in your adjectival list.
