Yes, it is possible.

Answer / pradeeshkumar
Yes, it's possible.
A foreign key in a table can have duplicate values.
For example, One or more employees can belong to same
project.EMPLOYEE_ID is the ptimary key of the Employee
table and PROJECT_ID is a foreign key that references
another table(Project).
EMPLOYEE_ID EMPLOYEE_NAME PROJECT_ID
