Brown stuff under fingernails is often a buildup of dirt, debris, and dead skin cells. It can also be caused by the accumulation of nail polish, food particles, or other substances that get trapped under the nails. In some cases, it may indicate poor hygiene or a fungal infection. Regular cleaning and proper nail care can help prevent this issue.
Fingernails start to grow right under the base of the cuticle. There are probably only a few millimeters underneath the skin.
It's you dead, hsrden skin!
Ya know. Stuff.
It protects the skin underneath it. Don't chew your fingernails because they are dead skin. Your skin produces this.
The brown stuff is their feces.
Fingernails do not contain tapeworm eggs. You might, in theory, have tapeworm eggs underneath your fingernails, but only if you have been handling feces and you didn't wash your hands afterwards.

The white spots underneath your fingernails are something like eternal bleeding. It would be fungi growing underneath your finger, because you had hit your finger against something.
