Answer 1

You can do this in following ways.
Submit your form with ajax and handle each form separately. In this way, every form will be posted in different links.
Put different URLs in the action for the two forms. Then you'll have
two different view functions to deal with the two different forms.
Read the submit button values from the POST data. You will have to send a parameter with which you can tell which
submit button was clicked.
forma = FormA(prefix="a")
formb = FormB(prefix="b")
which_form = request.GET.get('form_name')
if request.POST:
if which_form == 'a':
forma = FormA(request.POST, prefix="a")
if forma.is_valid():
obja = forma.save()
if which_form == 'b':
formB = FormB(request.POST, prefix="b")
if formb.is_valid():
objb = formb.save()

I've recently been fighting with a similar situation. I have a 'master' form which contains 3 'subsections' or 'subforms'. I thought of them as 4 forms for way too long. After searching a dozen SO posts.
I arrived at the following:
In the html, use ONE tag, which will POST to your view. You can use s or Bootstrap classes or whatever to make the HTML look like separate forms, but I only have/need one submit button. In your example, place {{aform}}, {{bform}}, {{cform}} and {{dform}} inside the single tag pair.
In the view, while building aform, etc, assign a prefix to each form class (https://docs.djangoproject.com/en/4.1/ref/forms/api/#prefixes-for-forms). In fact, that same point in the documentation says outright "You can put several Django forms inside one tag. To give each Form its own namespace, use the prefix keyword argument:"
In the POST processor of your view, use the same prefixes. This lets you resplit the combined POST data to aform, bform, cform and dform.
