Showing Details with Drupal Views 3
One of my friend suggested me to create three displays in views each showing result from each table i.e. first display to show the fee details, second fee instalments and third to show the fee students. Then in page display all three views by using the functions views_get_view. Thanks Inian :)

While doing the way Inian suggested, I found attachment as a display type and that solved my problem and I don't have to write any custom code now.
