The answer to your question is below. I have listed when you can use each in different tenses:
PRESENT TENSE
I have
you have
he has
she has
it has
we have
they have
PAST TENSE
I had
you had
he had
she had
it had
we had
they had
FUTURE TENSE
I will have
you will have
he will have
she will have
it will have
we will have
they will have
PRESENT PERFECT(from the past till the present)
I have had
you have had
he has had
she has had
it has had
we have had
they have had
PAST PERFECT (expresses the idea that something occurred before another action in the past. It can also show that something happened before a specific time in the past.)
Example – I had had nothing to eat at all, until my mother came to see me.
You cannot say ‘I have have’ – that is incorrect.
