1st of all red blood cells don't reproduce. They are not true cells because they dont contain a nucleus thus do not contian the genetic material needed for reproduction thus do not go through the cell cycle. They are just convex shaped carriers of hemoglobin(which in turn carry oxygen). They only live for about 40 days and new ones are made by cells in your bone marrow. Skin cells are real/normal cells. Skin cells divide/replicate more than normal cells because they are exposed to rough conditions( UV light, dehydration, overhydration,scarring and brusing) so many are killed that out body has to make new ones to replace old ones at a fast rate.
Cells in the dermis (skin) divide the fastest. You are always rubbing the top dead layer off and that has to be replaced. An interesting fact: most of the "dust" in your house is skin cells.
Children's cells divide more often because they are still growing and developing. This rapid cell division is necessary for tissues and organs to increase in size and complexity during childhood. As individuals age, cell division rates slow down.
Stem cells are different from other cells in the body in several notable ways. They can divide and renew themselves many times, whereas other cells are more limited in their divisions. And when those stem cells divide, the new cells can become specialized if necessary. Stem cells have no assigned function in the body, but through the process of specialization, they can take on roles in any of the body's tissues. These type of cells can be derived from human embryos or from certain spots in the adult human body.
Branching fibers refer to fibers or structures that divide into two or more smaller branches or strands. In biology, neurons in the brain often have branching fibers that help transmit electrical signals to other cells.
It's all part of a cell's life. The cell must split to reproduce. When the cells in your body split, you grow or they replace other dead cells. Reproduction is necessary for sustaining a living organism or population.
Skin cells are damaged faster than your liver cells so the divide more often
because the skin is constantly needing repair
Liver cells divide about once a year, and neurons (nerve cells) never divide once we are born (and when they are mature).
because the skin is constantly needing repair
No, they are just as sensitive as any other cell.

As far as I know, liver cells usually only undergo mitosis if the liver is damaged. You should check a few other sources though.
Cancer cells divide excessively and invade other tissues. They do not have density dependence or anchorage dependence. Simply put, regular cells grow in an even layer while cancer cells grow tightly and on top of each other - an unnatural mass.
They divide, it takes some long time.
