Yes, they are legal under State law. Idaho state law does not prohibit ownership of fully automatic firearms by private citizens. However, Federal law requires that any fully automatic firearm have been registered with the Bureau of Alcohol, Tobacco, Firearms and Explosives.

It is legal for a private citizen to own a fully automatic rifle in MOST US states IF you comply with Federal law (National Firearms Act- requires registration of full autos with the BATFE). Rather than list all the states that DO, why not post the state or states you are asking about?
Depends on where you live, how old you are, whether or not the rifle is registered with the BATFE. They can be owned if you go through the appropriate procedures unless you live in a state that doesn't allow it. but usually it is legal.
In general, fully automatic firearms are permitted. In additional to Federal registration, a State license may be required for "pistol caliber" machineguns. I would urge you to discuss this with the Firearms Technical section of the BATFE, and not seek legal advice from WikiAnswers- I am NOT an attorney.
Idaho does not prohibit possession of either a semi-automatic rifle, nor a fully automatic rifle (machine gun) Fully automatic firearms are regulated under Federal law in ALL states. Possession of a fully automatic firearm is legal in Idaho so long as the gun has been registered with the Federal BATFE.
Yes.
