1)No We can't have more than 1 primary key. Even if you try
to save it will pop an error message and nothing will be stored.
2)Clustered Index is attached with Unique. A table can have
1 and only 1 Clustered Index and it will be mostly created
on the Primary Key of the Table.
Non Clustered can be up to 254(not sure about the
number)created for a single table.
3)You can definitely select from 2 tables but all the
columns will be merged. Please check how you want the data
from those 2 tables
