    There are four different questions here! Maybe consider asking them one at a time? – Joseph Weissman Sep 28 '15 at 21:46

No, questions 1 and 2 are incorrect. Since this looks like homework, I'm only going to give you a hint.

The hint is: have a look at the definitions of validity and soundness in your textbook or online, e.g. in Validity and Soundness at the IEP.
