I would like to ask when should I use HAVE, HAS, HAD. DO, DID, and DOES?

Ola's answer:

I, you, we, they => HAVE (present)

He, she, it => HAS (present)

I, you, we, they, he, she, it => HAD (past)

I, you, we, they => DO (present)

He, she, it => DOES (present)

I, you, we, they, he, she, it => DID (past)
