Answer:
I'm guessing for #1 your talking about state law and federal. A federal law applies to the nation as a whole and to all 50 states whereas state laws are only in effect within that particular state. ... The law that applies to situations where state and federal laws disagree is called the supremacy clause, which is part of article VI of the Constitution.
For #2 you can go to congress.gov
#6 i think privilaged president
Hope this helps!
