Let's say, I use django.contrib.flatpages, or any other third-party app in my project. I want to change some of this app's model attributes - for example, verbose_name. How can I do that?

If you'd like to specify a custom primary key, specify primary_key=True on one of your fields. If Django sees you've explicitly set Field.primary_key , it won't add the automatic id column. Each model requires exactly one field to have primary_key=True (either explicitly declared or automatically added).
To use the model in the Django admin, we need to makemigrations and create the model that maps to a single database table. Now with the table created, we can migrate the model so all of the information uploaded to the model will be saved to the Django database, db.
An app name is just the name of the Python module. Nothing more. A python module name is the case name of the root folder of the module, that must contains an init.py file. If you want to know what this name is, go to your site-packages folder and look for your module.
The simple answer is "don't"; use a proxy model instead.

It depends. If you want to add some new fields, you can create another model with OneToOneField. If you want to add some methods, ordering etc., use proxy model. If you want to change some DB restrictions (e.g. max_length) you can patch the source code of the app, but think twice before doing that, you should have a really good reason for that.
If you want to change verbose_name, you can override label in corresponding form field, no change in model needed.
