The actual number of women diagnosed with hemophilia is very hard to pin down. Doctors do not even agree on what designates a female as having hemophilia. Some believe that both X chromosomes would need to have the mutation, while others diagnose using the clotting factor levels. Due to the occurrence of what some doctors call incomplete dominance by the non-affected X chromosome the mutation can lower a "carrier's" clotting factor below what would qualify any male as having 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.
All Girls will be carriers of Hemophilia. All Boys will be unaffected (they won't have Hemophilia).

Her father has to have hemophilia as well, and the mother is a carrier or also has hemophilia. So if we pretend that the hemophilia gene is "x", you need to have "xx" to have hemophilia. The father must have the genotype "Yx" and the mother has the have "Xx" or "xx".
There are no hard answers to this, it depends strictly on luck. The statistics are though not very good for their children. Statisically the couple have a chance of having a normal son, a daughter that is a carrier for hemophilia, a daughter with hemophilia and a son with hemophia.
It is possible but extremely rare.
Anyone can inherit hemophilia. In most cases, it is a man whose mother is a carrier of the disease. It is extremely rare for a woman to have hemophilia but it is not uncommon for one to be a carrier. It is even possible for someone whose family has no record of hemophilia to get it through gene mutations.
You would get it from your mother. It is a sex-liked genetic disorder. Females are the carriers, males exhibit the condition.
You have to be born with hemophilia, it is not something people can "catch".
