Is a many to many relationship possible, since I do not see a way

Yes. With Core Data you don't have to worry about primary keys,
foreign keys, etc. -- the framework manages the schema for you, and
does the right thing to represent your model.
A many-to-many relationship is really a to-many relationship from A
to B with a to-many relationship from B to A as its inverse.
