I will pick up the phrase which I feel doesn't make sense.

1,"ryoushite shite koto ni" :maybe "ryourisuru koto ni" ?

2,"kazoku you" :I can't catch the meaning...

"Satchu-san" :"Satchan" is more common, I think?

3,"minnna-san" :you already say "imouto-san", so it shoud be only "minnna".

If you show me what you want to say in English, I will advise you in detail, if you would like.

I hope this will help.
