Although I really do want to help you, Coolve-san, I do agree with Lanthas-san. Please try to post what you think you should do and then everyone can help you. I will give you a hint though. For the one about the name 名前 なまえ namae is used and desu is at the end. I will let you figure it out form there. Please do a little research and you should be able to figure it out. I do want you to learn and spoon feeding you all the info will only hurt you later on down the road. If you cannot figure it out by tomorrow I will be glad to help.
If you actually want to learn the language, there's no point in us giving you answers.
But I'll give you one: souzoujou no tomodachi ha chibikun to iimasu.
boku no atamano naka ni sundeimasu.
chibikun ha uchuu kara kimashita.
P.S. I suggest creating answers based on the examples you learned (not these).
