Some of your DNA will be the same! You are likely to have somewhere between 1/8th and 1/16th of the same DNA.
You would share approximately 12.5% of your DNA with a first cousin. This is because you share a pair of grandparents with your first cousin, resulting in genetic similarities but less than with a sibling.
You share approximately 0.78% of your DNA with a third cousin. This is because third cousins share a common ancestor who is your great-great-grandparent. The amount of shared DNA is relatively low compared to closer relatives like siblings or first cousins.
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 share more DNA with your son because you pass on half of your DNA to your child, while siblings share, on average, half of their DNA, but it can vary due to genetic recombination.
Cousins would share up to 50% of the DNA.

first cousins CANNOT have the same DNA. siblings share 50% of their DNA, and first cousins share 25%. I'm not sure which test you are refering to, as 99.9% DNA match would infer identical twins.
from 3.125% to 50%
You share some DNA with everyone to whom you are related. Since you have a common ancestor with your father's cousin twice removed, you are related and share DNA. More broadly, every human being has large amounts of DNA that are shared with every other human being. That is what makes us humans, as distinct from chimpanzees, orangutans, gorillas or mice.
No, half siblings do not share the same DNA. They share only one biological parent, so they have some genetic similarities but also differences in their DNA.
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.
No, monkeys do not have human DNA. While humans and monkeys share a common ancestor, their DNA is not the same.
You share more DNA with your son because you pass on half of your DNA to your child, while siblings share, on average, half of their DNA, but it can vary due to genetic recombination.
Assuming no inbreeding, the current descendent would have only 1/64 (less than 1.5%) of his ancestors DNA.
