Queries on twitter data extarcation


#1

1)Firstly I would like to know would it be possible for me to extract twitter data for the last three months. For example giveing a date rage I.E 18 march 2013 to 18 june 2013.
2)secondly it states that you get 15 queries every 15 minutes per application. so does that mean that one GET method counts as one query.
3)if two is true is it possible for an application to get more queries.
4)with the twitter API data is it live or 24hour or longer old
