100%
You share around 0.2% of your DNA with a fourth cousin. This is because fourth cousins are about five generations removed from a common ancestor.

Humans and chimpanzees share about 98% of the same DNA. So, you would share roughly the same amount of DNA with Bonzo, the chimp co-star of Ronald Reagan.
You probably share about 50% of your DNA with a sibling. Theoretically, it could be as low as 0 (though that is extremely unlikely). Identically twins share 100%. You always share close to 50% with each parent. But if you are male, you actually have a slightly higher percentage from your mother (because the X chromosome is larger than the Y).
Not much- probably only about 25-30%.
