All Girls will be carriers of Hemophilia and all Males will be unaffected (they won't have Hemophilia).
There is no chance that the child will have hemophilia even if the spouse has hemophilia. Any girls the couple has will be carriers if the spouse has hemophilia.

Yes. Parents can be carriers of MANY different diseases.
yes hemophilia can be detected before birth
XhXh - with hemophilia XhXH- carrier of hemophilia
Mary's father is normal and has a normal genotype XY while her mother is the carrier of hemophilia and has one X of her genotype infected i.e. she is X*X.
The probability is zero! There is no such thing as "normal". Every child (and adult) has some unique characteristics and that makes them not normal - in that respect.
It is possible to diagnose Hemophilia in the fetus during pregnancy by demonstrating the abnormal gene.
No, having a child does not change the age of the minor and it does not grant emancipation.
If both parents have x-linked hemophilia, the father's genotype would be XhY and the mother's genotype would be XhXh, which is astronomically rare. If this did happen, all of their children would inherit x-linked hemophilia. Hemophilia is passed down from mother to son. It is extremely rare for a woman to have hemophilia. It is necessary, though, for a woman to be a carrier of the disorder for her son to acquire this disorder. Females have two X chromosomes whereas males only have one. When a boy is born, he takes one X chromosome from his mother and one Y chromosome from his father. Therefore, he can only get hemophilia through his mother. Example One: Mother(Carrier)+Father(Non-Affected)=50% chance of their son acquiring the disorder and 50% chance of their daughter being a carrier. Example Two: Mother(Non-Affected)+Father(Hemophiliac)=All sons will be non-affected and all daughters will be carriers.
yes. chances of getting a normal child is 50/50
If the female has what is classically defined as female hemophilia (carries the mutation on both of her X chromosomes), then all sons she would have would also have hemophilia. All of the woman's daughters would also inherit the gene, however since they would also be getting a normal X chromosome from their father, they would not, themselves, have hemophilia under the classical definition. Today, it is understood that even carrying the trait on a single X chromosome can reduce a female's factor levels and give cause for doctors to diagnose her with hemophilia. Thus if you are simply looking at genetics (which you probably are) then the answer is all of her sons would have it and all of her daughters would be carriers. Therefore, since there is a 50-50 chance the first child bore would be a male, and a 50-50 chance it would be a female, the chance that their first child born would have hemophilia is 50%.
