no.
Not only do different human bodies have different pH, but different parts of the same body have different pH also. There are a variety of different chemical environments within a single body.
The Ph. of all human blood is the same. Different races of people do not possess different Ph. balances of their blood.
No.
no it depends on what your bmum says
Personally no. I'd imagine enzymes throughout the body have environments that have varying pH levels. Although, pH is how many hydrogen+ ions there are. Many cells in the body may have the same or very similar pH levels but some parts of the human body may have higher or lower levels, meaning that the optimum pH for the enzyme depending on which part of the body it catalyses within.
The optimum pH for human catalase is approximately 7, and has a fairly broad maximum (the rate of reaction does not change appreciably at pHs between 6.8 and 7.5). It doesn't work as well above 7.5 or below 6.8.
Hair hasn't a pH.

No, solid compounds do not have a pH. pH is a measure of the acidity or basicity of a solution, not a solid compound. The pH of a solution can be affected by the solid compound dissolving in the solution.
According to forensic scientists, decomposing bodies in soil tends to raise the ph. levels because the body releases ammonium ions which cause soil to become more acidic.
No. It does not have neutral pH. It has got some what alkaline pH.
Yes, all titrations of a strong base with a strong acid result in the same pH at the equivalence point, which is around 7.
Yes, e.g. human skin is between pH 4.5 and pH 6.
