Of course it is possible. When you create the fields in the init
method, make sure they are given distinct names. Store the names of
the generated fields in a list on the form object, and then provide an
iterator method that yields the variable fields in the order you want.
Eg:

class MyForm:
def __init__(self, *args, **kwargs):
self._variable_fields = [ ]
for ....:
field_name_id = 'field_name_%d' % val_id
field_email_id = 'field_email_%d' % val_id
self.fields[field_name_id] = forms.FooField(...)
self.fields[field_email_id] = forms.FooField(...)
self._variable_fields.append((field_name_id, field_email_id))

def variable_fields(self):
for field_name_id, field_email_id in self._variable_fields:
yield self[field_name_id], self[field_email_id]

In your template:

{{ form.static_named_field1 }}
{{ form.static_named_field2 }}

{% for field_name, field_email in form.variable_fields %}
{{ field_name }}
{{ field_email }}
{% endfor %}

Hope that helps

Cheers
