Does redundancy exists in this table?
Redundancy does not mean:


Columns that have the same data type
Columns (or rows) that have the same data value (if this is coincidental)
Columns that are foreign keys that link a child table to its parent (including the same data value as FK and PK in the respective tables)


Redundancy is not about columns or rows for that matter.  Redundancy is about functional dependencies.  If you have predicates (i.e. columns) that are transitively dependent, then you have redundancy.

Hunting for redundancy is a bad approach when optimizing a logical data model.  Trying to decide what is and isn't redundant is tricky and frankly a little bit beside the point.  Focus on normalization.  This will eliminate your redundancy along with other potential problems along the way.  

When you move from logical model to physical database, you can then determine whether managing some redundancy is worthwhile for some reason.
