Casually asking for a person's name, more natural than 名前は何ですか。


I just [learnt](https://japanese.stackexchange.com/a/14453/107) that
「名前は何ですか。」 sounds non-native.

What would sound more natural?  
Let's say I am addressing a friend of a friend, same age, after a futsal game
where we talked together without being formally introduced.




To take the "casually" part literally, you could say:

「（お）[名前]{なまえ}は？」

「（お）名前、[聞]{き}いてもいい（かな）？」 or 「（お）名前聞いてもいいっすか？」

「なにさんって[呼]{よ}んだらいいのかな？」 or 「なにさんって呼んだらいいっすか？」

「（お）名前[教]{おし}えてもらえる（かな）？」

, etc.
