Does a pair always means '2 of something' or can it be used more generically to indicate 'a few of something'? What is the exact amount indicated by 'a pair'?
Is there a different meaning whether a pair is used in formal or in informal language?

The OP is asking whether "a pair" can signify more than two things. Generally speaking it cannot but there will always be the odd exception; however, for now none come to mind.
The term couple is less fixed:
I'd like a couple of oranges, please.
This can suggest any number of oranges between two and four.
But a pair (of) will nearly always be two of something that are parallel to each other. They will look identical to each other and will be used together.
