1.There cannot be more than 1 Primary Keys for a given table?
2.Difference between Cluster Index and non-Clustered Index, check this link: http://sqlwithmanoj.com/2011/03/02/clustered-vs-nonclustered-indexes-and-data-sorting/
3.Yes, we use query like this "Select * from Table1, Table2;". This will give a Cross Join (or cartesian-product) results from both the tables.
