Modal auxiliaries do not be used together or with another auxiliary. You have to use it at the beginning of a question or you have to put them after the person and before the verb. These are the modals we will check.

Note: We use after WOULD or WOULDN’T the verb in simple form.
SHALL. This is not common nowadays but sometimes people can use it. You can use SHALL in different ways.
1. As a Future action (WILL or Going to)for I and We. Sometimes it refers to suggestions. In future events it often expresses inevitability or predestination.
