This question cannot be answered because the term "half-cousin" has no meaning.
Presumably, the term is intended to be analogous to half-sibling, where children share one but not both parents. In the case of cousins, however, the relationship derives from a single common ancestor, and you can't have half of one common ancestor.
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.
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 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 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.

A half-niece and her uncle are expected to share about 12.5 of their DNA.
A person and their half-uncle are expected to share about 12.5 of their 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.
Cousins would share up to 50% of the DNA.
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.

You share approximately 50% of your DNA with each of your biological parents. This is because you inherit half of your DNA from your mother and half from your father during the process of genetic inheritance.
Humans share approximately 98-99 of their DNA with other animals.
