이름이 뭐예요? (common form; used in more of a casual setting and perhaps with someone closer to your age) 성함이 어떻게 되세요? (more polite form; used in a more formal setting and perhaps with someone who is noticeably older than yourself) 이름 = name (common form) 성함 = name (formal form) 뭐예요? = 'What is...?' (common form) Hope that helps!

i'd say "이름이 어떻게 되요?".(nama sapa?) this is more common and natural in spoken. for formal, "성함이/이름이 어떻게 되세요?"(Siapa nama awak?)

There is a honorific in Korean. When you ask a name in a honorific expression, It is the sentence "이름 좀 알려주세요~" (=Could you let me know your name?" When you ask your firend's name "이름이 뭐야? "(What's your name)

How do you ask for names? In English : What's your name? In Korean : 당신의 이름은 무엇입니까? (direct translation) 이름이 뭐에요?(general expressions) In English : May I ask your name? In Korean : 당신의 이름을 물어봐도 되겠습니까?(direct translation) 성함이 어떻게 되시나요? (polit expressions)
