Skin cells are damaged faster than your liver cells so the divide more often
Liver cells divide about once a year, and neurons (nerve cells) never divide once we are born (and when they are mature).
Labile cells (the kinds of cells that can divide throughout their lifetime) normally do so within the organ they constitute. Some examples of labile cells are skin cells, cells of the gastrointestinal tract, and blood cells; however, blood cells divide in the bone marrow and lymphocytes divide in the lymph nodes. Other kinds of cells in the body are either stable cells (that do not normally divide--this includes nerve cells) and permanent cells (that do not have the ability to divide.)

Any cell that is not a sex cell (sperm/egg). i.e. body cells, such as skin cells, stomach cells, liver cells
No, cells undergoing meiosis take longer time than those undergoing mitosis
In neurons. Also liver cells typically don't divide, but can start dividing if a serious damage is done to the liver.

This depends on the type and grade of cancer. Some cancers divide and spread quite quickly, others may take quite a bit longer to become clinically significant.
