It varies dramatically depending on what type of cell it is. For example, blood cells and skin cells are constantly being replaced, so they don't live for very long. However, your brain and nerve cells NEVER get replaced, so they live until you die. That's why if you hurt your spine in, for example, a car wreck, you are likely paralyzed for life, whereas if you scrape your skin it will grow back.
The cells in your body that tend to last the longest are typically neurons and heart muscle cells. Neurons can last your entire lifetime, while heart muscle cells have a relatively long lifespan and are not replaced frequently.
Theoretically, with the proper preservation in a lab, stem cells may last indefinitely. The first cell lines still exist. In the body, one produces undifferentiated cells in their marrow up until death.
Brain cells, particularly neurons, are known to have a long lifespan and turn over the least frequently compared to other body cells. Some neurons can last a lifetime without being replaced, unlike other types of cells in the body that have a faster turnover rate.
Skin cells on the body typically live for about 2-4 weeks before they are shed and replaced.
The longest cells are neurons (nerve cells) linking the central nervous system (brain and spinal cord) to other parts of the body. For example, for every receptor cell in your feet, there is a sensory neuron extending from the foot to the base of the spine.

The human body can last about 3-4 minutes before cells begin to die.
Forever

Yes
Cocaine may last in your body for about 15 hours.

in long bones
no some cells only last a few days or hours while some can last for years at a time
The name of the long cells that can stretch and contract in the body are called muscle fibers. These fibers make up our muscles and are responsible for movement and generating force in the body.
According to a healthy lifestyle book that I just read recently, it is in theory (not proven yet) that they last for approximentally 4 months. Your body is always making new blood cells, so there is no need to worry if you have a healthy & active lifestyle.
