Some of those questions don't make any sense. What does "being in a vacuum" have anything to do with weight? I suppose they mean being in a place where the gravitational field is zero, but that's pretty silly.

First these look like homework and probably should be in the homework section.

Secondly, they all are really based on the definitions of mass and weight which should be in your textbook.

badboyben03, how about quoting the definitions of mass and weight you are using for us?
