According to the above singular and plural forms of Nouns and Pronouns the Helping Verbs like 'Be' forms, 'Possessive' forms and 'Do' forms are changed.
But coming to Modal Auxiliaries they are not changed according to the form of Subject / Object. They are used according to the following concepts.
In-fact Modal Auxiliaries reflect our Personality means our Probabilities, our Responsibilities, our Abilities, our Manners, our Braver and our Habits are shown by them.
Will / Shall -------- say our Future Ideas.
May / Might -------say our Probabilities.
Can / Could ------- say our Abilities.
Should / ought to / Must ------- say our Obligations or Responsibilities.
Need to ----------- say our Necessity.
Dare to ------ ---- say our Bravery.

IMPORTANT NOTE: That means when we want to learn how to convey our views in English, we must learn to say each and every view related to present and past and with Modal Auxiliaries. That means we have timely related views and personality related views.
Timely related views are said by 'be' forms, 'possessive forms and 'do' forms. Personality related views are said by Modal Auxiliaries.
