Technically yes, but 'Buku itu saya baca' is much more natural for first and second person. 'Dibaca oleh...' is usually reserved for third person (e.g., 'dibaca oleh Budi').
No, for 'Dia', you must use the 'di-' passive: 'Buku itu dibaca dia' or 'Buku itu dibacanya'. You cannot say 'Buku itu dia baca' in formal Indonesian.
Not exactly. While it functions similarly to the passive, in Indonesian, 'Object-Focus' is a distinct 'voice' used specifically for 1st and 2nd person agents. The standard passive uses the di- prefix and is for 3rd person.
In informal speech, yes. In formal writing, you should use the passive: Buku itu dibaca Budi.
No, it sounds unnatural and is grammatically incorrect.
In modern Indonesian, it is often separated when meaning 'also'.
