Comfort and cheer
What you say back to someone's news: relief, a shrug, encouragement, denying a put-down, and congratulations.
yokatta
polite yokatta desuphew, that's good
よかった よかったです
Relief or gladness at an outcome ('yokatta, ma ni atta'). About someone else's news, it means 'I'm glad for you'.

shouganai

Oh well, let's go again tomorrow.
しょうがない、また明日行こう。
shouganai desu ne, mata ashita ikimashou.
It can't be helped. Let's go again tomorrow.

ganbatte

Good luck on tomorrow's exam!

ashita no shiken, ganbatte kudasai.
Good luck with tomorrow's exam.

Said to a boss, it can sound a little presumptuous. To someone already struggling, muri shinaide (don't overdo it) is kinder.
