No, only in formal writing or speech. In casual conversation, you can just use rising intonation.
No, that is grammatically incorrect. It should be at the start or attached to the question word.
It is one word, a combination of 'apa' and '-kah'.
If you are speaking, it is fine—people will understand you from your tone. If you are writing, it might look unprofessional.
No, it is invariant. It is the same for 'saya', 'kamu', 'dia', etc.
'Apa' is the informal version. 'Apakah' is the formal version.
Yes, 'Apakah kamu tidak lapar?' (Are you not hungry?).
It is standard in formal Indonesian, but regional dialects have their own ways of asking questions.
