In creo,Is it possible to control orientation of coordinate system in family table(X,Y,Z AXIS)?
Absolutely! Create your new coordinate system then create a family table. When you add the columns to the table make sure Dimension is the choice and pick your new coordinate system. You should see all 6 values (X,Y, Z translation and rotation dimensions) that you can select and add to/manage in your table.
.... and for clarity of those who use your model in the future rename the dimensions (d18, d20, d8..... to X translation, X rotation, ..... or whatever other names you use).
