Practice and hit balls at the driving range.
Nothing. They can legally be played on the PGA tour.

Possibly. Many golf clubs and driving ranges use "limited flight" balls. This requires less space for the actual range itself. The "range ball" is designed in such a way (with shallower dimples) that prevents it from flying as far as a "standard" flight golf ball. Range balls also typically have a harder cover, making the ball more durable (but less forgiving and further decreasing its flight). Ask the pro at the club or an employee at the range, and they should be able to tell you what kind of ball is used (limited or regular flight).
Its your balls!!

No, Driving range is an activity, and golf is a sport. The reason why Driving range is an activity and not a sport is because that is just a way to test your accuracy, your new clubs, and to see how your improving.
They are usally high compression very low quality two piece balls.
Well it depends how dedicated you are to it. You have the revenue from the buckets of balls, drinks and snacks, golf lessons if you are qualified to give them, club fitting (re-shafting, re-gripping and custom fitting) and equipment sales (clubs, balls, gloves, tees, and even clothing).
Go to a driving range. Distances are clearly marked. You will need to hit several balls with all the clubs several times to get an accurate average.
