Casual, direct. Used among friends, family, or in informal situations. Often with rising intonation.
What's this?
What's that?
Polite form. Use with strangers, superiors, or in formal settings. The ですか adds politeness.

What the heck is this?

You look pale, what's wrong?
Polite version of どうしたの. Suitable for formal situations or when speaking to someone you don't know well.
What's the matter?
Casual, implies 'did something happen?' Often used when you suspect a problem.
Did something happen?
When someone refers to something and you need them to specify what 'it' is.
Casual. それって emphasizes 'that thing you just mentioned'. Very common in conversation.
What's that? (that thing you mentioned)
Polite version. Use when you need clarification in a formal context.
What is that?
Casual. Means 'What are you talking about?' or 'What do you mean?' when you don't understand the reference.
What do you mean?
When someone knocks on the door or calls your name, and you respond 'what is it?' meaning 'who is it?' or 'what do you want?'
Polite and neutral. Used when answering a knock or when someone calls you. Equivalent to 'Yes?' or 'What is it?'
(to a knock) Yes? / What is it?
Casual, can sound abrupt. Use with close friends or family when they call your name.
(when called) What?
Very polite. Used when answering the door or phone to ask 'Who is it?' Literally 'Which honorable person is it?'
(at the intercom) Who is it?
In Japanese, 'it' is often omitted. Saying それは何ですか is fine, but in many contexts just 何ですか or even 何？ is more natural. Don't force a pronoun when it's clear from context.
Rising intonation on 何？ or 何ですか？ makes it a question. Flat intonation can sound like an exclamation ('What!').
あれは何ですか？
What is that over there?
