Get on a very long waiting list to get your green card. You wouldn't be an alien if you were legal
Doubtful. Relationships do not change immigration status.
Absolutely not.
Absolutely not.
No.
Marriage is recognized by the US , but they must report it when they get home. It does not affect their alien status.

Sure they can marry, but no felon from a foreign country can gain legal entry into the United States, much less legal status. They are persona non grata.
Of course! Being married does not affect one's legal status, even a legal alien can be deported for criminal activity.
No. He or she can and will be deported when the authorities notice his or her legal status.
If by "legal alien" you mean a "resident alien" (i.e., a foreigner with permission to live in the United States) and by "alien" you mean any alien, whether legal or illegal (undocumented), then the answer is yes. Generally, there is no citizenship requirement for marriage in the United States. What effect the marriage will have on the immigration status of the parties involved is another question.
The age at which someone can marry an illegal alien is based on the law of the state. Anyone can legally marry if they of legal age. Most states put the age at about 18.
Yes, as well as being a FEDERAL CRIME, it is immoral and destructive to the country. The legal alien also risks revocation of their legal status and deportation. If the illegal doesn't care enough to do things legally, who the heck wants them here? What kind of citizen (other than selfish, greedy and irresponsible) will they be?
