Yes those questions can be asked if you are interviewing for intern/junior dev position.
If you are interviewing for senior dev position, more design/optimization questions are asked.

Not really. Nothing you’ve listed is really ‘senior’

Yes I have only mentioned common react questions, not HLD or LLD questions.

Depending on the answers to my questions, I know: the above would really show an understanding of how react works and therefore an ability to:

know how react decides to re-render (e.g. referential equality)
know when & why to use imperative escape hatches over the declarative nature of react
know when & why to optimize performance

Subjects I would not really expect a junior/intern to know much about.

Its all about what are requirements of developers in which country.
In my country, even interns are required to know

When to use useState/useRef?
How to use useEffect?
When/How to optimise using memo/callback?
