5. How to set ordering of Apps and models in Django admin dashboard.

Django, by default, orders the models in admin alphabetically. So the order of models in Event admin is Epic, EventHero, EventVillain, Event

Instead you want the order to be

• EventHero, EventVillain, Epic then event.

The template used to render the admin index page is admin/index.html and the view function is ModelAdmin.index.

def index(self, request, extra_context=None):
    """
    Display the main admin index page, which lists all of the installed
    apps that have been registered in this site.
    """
    app_list = self.get_app_list(request)
    context = {
        **self.each_context(request),
        'title': self.index_title,
        'app_list': app_list,
        **(extra_context or {}),
    }

    request.current_app = self.name

    return TemplateResponse(request, self.index_template or
        'admin/index.html', context)

The method get_app_list, set the order of the models.:

def get_app_list(self, request):
    """
    Return a sorted list of all the installed apps that have been
    registered in this site.
    """
    app_dict = self._build_app_dict(request)

    # Sort the apps alphabetically.
    app_list = sorted(app_dict.values(), key=lambda x: x['name'].lower())

    # Sort the models alphabetically within each app.
    for app in app_list:
        app['models'].sort(key=lambda x: x['name'])

    return app_list

So to set the order we override get_app_list as:

class EventAdminSite(AdminSite):
    def get_app_list(self, request):
        """
        Return a sorted list of all the installed apps that have been
        registered in this site.
        """
        ordering = {
            "Event heros": 1,
            "Event villains": 2,
            "Epics": 3,
            "Events": 4
        }
        app_dict = self._build_app_dict(request)
        # a.sort(key=lambda x: b.index(x[0]))
        # Sort the apps alphabetically.
        app_list = sorted(app_dict.values(), key=lambda x: x['name'].lower())

        # Sort the models alphabetically within each app.
        for app in app_list:
            app['models'].sort(key=lambda x: ordering[x['name']])

        return app_list

The code app['models'].sort(key=lambda x: ordering[x['name']]) sets the fixed ordering. Your app now looks like this.
