I'm trying to connect Django with MongoDB database. Why am I getting these warnings while migrating?

An old question but you can solve the problem with installing specific pymongo version.

Try this one:

pip install pymongo==3.12.1 --upgrade

Then try to make migrations again.

MongoDB isn't supported by the Django project itself, only via the Djongo adapter.

Those models/migrations use certain Django core features that Djongo doesn't support at present, as is rather obvious from the error message.
