probably ingrown hairs. If the hairs are cut short (below the skin) they can grow under the skin and become infected.
I think that it will grow a new body (don't know how :/ )
Yes you can. It might make it slightly harder for the dentist to remove but will not be a problem. Grow a pair.
Kids should grow to become more mature adults in the future.

When a wart gets infected, it may become red, swollen, and painful, and there can be an increase in pus or drainage from the area. The infection can cause the wart to grow larger and may lead to additional complications, such as the spread of the infection to surrounding skin. Infected warts may require medical treatment, such as antibiotics or drainage, to resolve the infection and alleviate symptoms. It's important to avoid picking at or irritating the wart to prevent further infection.
they grow up to 50cm then they become in to trees
Depending on the depth of the cut. There are a few amounts of layers of skin at one point if cut deep enough you will reach the layer where the hair begins to grow. The eyebrow is a very sensitive location because it does not have as many layers of skin there for hair that grows is reasonably close to the top layer (your eyebrow skin) so most likely unfortunately if it was just a scratch it will grow back. If it required butterfly stitches or regular stitches then no the hair will not grow back but the scar will heal and may not even be that noticeable. Hoped this helped.
