I would say that it is okay for you to say that... but i would not brag about it..
You can say "C'est bon" in French, which translates to "That's okay" in English.

Are you speaking of the term 'Okay' (or O.K.)? It is, in English, an affirmative acknowledgement. For example: Your employer asks you to clean the coffeepot in the breakroom. You can say: "I will." "As you wish." "It will be done." but often in English speaking countries you can simply say the slang "Okay."
Okay in Indonesian is oke. You could also say yameaning yes.
I guess you could say 'sufficient/okay'.eg. Ikaga desuka? Is this okay?
In classical Greek you say mathitis. In modern Greek you say spoudastis.
i say, lack of confidence to speak...
I'm not sure what you are trying to say. As an English sentence it doesn't mean anything. Are you trying to say "Nick is the best student in English classes"?
It's not proper English, no. What is it exactly that you want to say?
Just like that. You say, "Is she okay?"
Majority of Singaporean can speak English, so a simple "Hi", or "Hello" is good enough
ça va ! à plus. I'm okay, see you later.
