To say good morning in Dhivehi, you have to say "goedemorgen".
Of course you can. I said it at a party yesterday and a good time was had by all. You can also say "is had" (When we party a good time is had by all.) And you can say "will be had" (When the party starts a good time will be had by all.)
They have slightly different meanings. If you are speaking of English as a language, you would say "good at." If you are speaking of it as school subject, you would say "good in," just as you would say "good in science" or "good in history."
