no, the person is an illegal immigrant, not a felon
Yes you CAN marry, but that will NOT give him LEGAL status.
No it will not be easier to get a green card. And how did they illegally marry? If they were issued a marriage license, and they did not lie on the application, they are legally married.

If the immigrant is a true illegal (i.e. entered the country illegally/without inspection) even a marriage to a US citizen wont prevent him from facing possible deportation. Moreover, an immigrant CANNOT apply for citizenship, they must first apply for legal residency
the US citizen shouldn't
Regardless if you are in the military or not, once you marry an illegal immigrant with a marriage of a year or longer, they are legally U.S. residence thereafter.
It is legal in the United States for an illegal immigrant to marry a US citizen. Once the marriage is legal, the illegal immigrant becomes a legal immigrant and can stay in the US for the course of the marriage.
I believe you used to be able to marry an illegal immigrant and they would not have to leave but with the changes in federal laws for national securit I believe that has changed now and they would have to apply for citizenship like everyone else
I don't understand your question. Marriage fraud to violate immigration law is illegal and a felony. It is illegal to marry someone to make them legal. It is not illegal to marry an illegal immigrant because you love them. It is not illegal for you to immigrate your illegal spouse...assuming that the marriage is legitimate. It is illegal to mar them.
No, and the laws regarding marriage to an illegal immigrant become more draconian every day.
