Keep these points in mind:
Dual pronouns refer to exactly two people
Plural pronouns refer to three or more people
'we' / 'us' can include the listener or exclude the listener
Gender is not specified
One form per pronoun (not 'I' / 'me', just 'ahau')'
There are a variety of ways to look at pronouns. You will definitely find other methods and formats online and in books, but at different times - when trying to fix them in my head - I found the following helpful.
Here is a bit more information on the dual and plural pronouns, to help make sense of who each refers to:
she / her,
he / him
we / us,
us two,
both of us
we / us
(but not you),
we / us (but not you),
us two
(but not you),
us two (but not you),
me and her,
me and him
you,
you two
they / them,
those two
we / us,
all of us
we / us
(but not you),
we / us (but not you),
me and them,
the rest of us,
ll of us
(but not you),
all of us (but not you),
you,
you all,
all of you
If you prefer a more structured table, read down the columns (au, koe, ia, tāua, māua...) to see who is being referred to and how many people are included. Read across the rows (tāua, tātou, au, māua...) to compare which people are included or excluded in each pronoun.
