Teja, First, let me suggest you just copy and paste your models from models.py. People who use Django a lot may find it easier to read the code (because they are familiar with the syntax and layout) than your typed summary of the classes.
Second, Django by itself cannot do what you want it to do. Django just makes html pages from the models, views, and templates you define, or are found in the admin classes. Once a page is displayed, that is what you get until the page is re-loaded from the server. What you are trying to do is have the page change without a round trip to the server. For that, you need some form of Javascript talking to the server as well. You can change the contents of an html page based on a selection in a select box using some Javascript to detect the change in the page and then talks to a Django view; the view in Django gets the data you want from the database and returns that data to the script, which updates the html page; and an appropriate url for the script to talk to the view and for the view to listen to. That is just one way to accomplish what you want to do. There are also add-on django projectst that will do this for you. Google for django smart selects, django autocomplete, django ajax, and this page of projects - https://djangopackages.org/grids/g/auto-complete/. Good luck!
