Yes, you can get this notification from same department and extension of 5 years for govt employees.

Can you give me that government post advertisements details when it was published for both central and state levels. Do let me know for which department those post are opened and currently in which department you're working and from since when.

18–28 years and in some cases 22–30. The minimum age required to apply for Central Government jobs is 21 years and the maximum age is 30 years in certain cases. 

Yes there is age relaxation of 5 years for central govt employees under unreserved category.
