how to create a cluster key?

By definition, there can only be ONE primary key in a table. You can have other keys with various attributes, but there can only ever be one primary key.

Have a look at the composite primary key concept - http://weblogs.sqlteam.com/jeffs/archive/2007/08/23/composite_primary_keys.aspx[^].

Good one. From the keys in the question, it looked like OP wanted multiple primary keys, not a composite key.

Thanks. If that is the case, then your comment is the right answer - there can only be one primary key.
