No

S we can create its called composite key

ALTER TABLE TableName
 ADD CONSTRAINT CONSTRAINT _Name
  PRIMARY KEY (attribute1,attribute2)

no,we can't create two primary key's in 1 table.

No, we cannot create more than one Primary key for a table. 
Composite Primary key as mentioned in the answer by 
Purushotham consists of more than one columns together 
making a Primary key. In such a case the columns may be 
more than one but the Primary key is one.

No, we can't create two primary keys for a table. A table 
contains only one primary key.
A table can have one or more unique keys.

It depends.
but we can use 2 primary key per table.

no, we can't create more than 1 primary key on a 
table .Monalisa Behera is correct we can add more than 1  
columns together to make primary key.Srry misleading in 
earlier post
