"Who has had a..." is a grammatical structure (present perfect tense) asking about a singular subject (he, she, it) possessing something or experiencing something up to the present; the answer depends on the specific thing someone "has had," like a "busy day" (@She has had a busy day) or "this disease" (@He has had this disease), requiring context for who the "who" refers to.
The commonly repeated advice for remembering whether to use who or whom is this: If you can replace the word with he or she or another subject pronoun, use who. If you can replace it with him or her (or another object pronoun), use whom.
"Has had" and "have had" have the same meaning, but they're used with different subjects. "Has had" is used with singular first person (he, she, it, John, Akira, Priya, etc.) and "have had" is used with first person, second person, and plural third person (I, we, you, they, Jeff and Lee, etc.).
As a main verb, use have/has for the present tense and had for the past tense, as shown in these examples: I have a muffin and a cup of coffee. Yesterday I had a piece of toast and a cup of tea.

We use I/you/we/they + have got or he/she/it + has got to talk about things that we have. In many situations, have and have got mean the same thing. Have got is a little less formal than have. We often use have got more in speaking and have more in writing.
Give some examples of the present tense.
There are three main verb tenses in English: present, past and future.
The present perfect tense is the most difficult tense in English because there are so many unpredictable situations and contexts which throw a spanner into the works of the 'current relevance' argument.
There are 12 verb tenses in the English language:
Ex. I had had enough to eat but I wanted dessert anyway. The first had is the auxiliary (or helping) verb and the second had is the V3 (or past participle) of the main verb to have. It means that even though I ate enough, I wanted dessert after that.
Using 'Had better': How and When to Use in English
When you refer to an individual by name, you're using the third person singular—that means you use has. That's because names take the place of "he" or "she" (or any other singular pronoun, like the non-binary pronoun, "they") in a sentence. He has a dog.
Remember that has is used with singular subjects (he, she, it) while have is used with plural subjects (we, they).
