"jupanu" may be "sir or Miss" !?
it's a term of courtesy

Yes, but I don't know.
"Jupanu'" seems to be here a colloquial 'nickname'/ slang term

I agree. It's slang.

Yes, but in this case "jupanu" doesn't have the meaning of "master". Some people use it as a way of addressing to each other, in a very informal way. So "master" is actually not correct.
In rest the translation is ok, I didn't find it fair to vote against only for one word.

So what will it be?
"man", "guy", "person"?

Hi Lilian,

Yesterday, I translated this one too, but I was not fast enough. I used "guy". Hope this helps.

Can be "guy" or even "friend".
