Answer 1

mysite/setting.pyに以下のように追加してみてください

INSTALLED_APPS = [
    'polls.apps.PollsConfig',
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'polls',#追加してみてください

]

Answer 2

polls.modelではなく、polls.modelsではないでしょうか。

Answer 3

polls/modelsですね
views.pyも間違ってますよ
