2. Yes sure you have people with regular metabolisms. You should look at it more as a spectrum rather than three categories.
3. Yes. Exercise is a good way, particularly when it includes resistance training since that is a great way to increase lean muscle mass. Other things that also affect the metabolism are: exposure to a colder climate; certain foods (e.g. hot and spicy foods); eating frequently during the day; getting enough rest; drinking enough water.
4. You can affect your metabolic rate substantially. However it is not a change that occurs overnight and may require a lot of work. Now make no mistake, there is a strong genetic factor here, which will make it harder on some. However with discipline one can affect the body quite profoundly.
