if the girl and your sibling are the same age or the girl is younger, it could mean that the girl wants to get to know you to get closer to your sibling. If your sibling is a girl it could mean she idolizes her or something like that, (or shes a lesbian and the same as above) Otherwise she could just be making conversation hope this helps :)
No, because what if the boy asks a guy and what if the girls asks a girl? So the answer is no, but it depends on how the person will look when asking the question.
Shes in to you
It means she doesn't know who she is to you.
They like you
it possibly means that the girl likes YOU!

It means that since the guy moved on he asks the girl if she has moved on to to have now made her now let down easily.
To be his regular girlfriend.
