Yes it is possible depending on her age. I know this family who little sister got her periods before the older one. The little one was 13 and the older one was 15. So it may or not happen. If your sister is between 9 and 16 then she can get them
In Mandarin Chinese, you would say "妹妹" (mèi mei) for little sister.

Your little sister can be taller than you when she's older. If your sister takes after your dad and you take after your mother, you may be shorter than your sister as you get older.
Sometimes. Every girl is different and unique in their own way. Some girls get their periods the same time their mom did and some just get their period on their own time. Little sisters may get their period the same time their big sister got her's, but it depends. So yes, sometimes girls get their periods the same time their mom did or a close relative. (sister, mom aunt, grandmother, ect.)
You may say 'imouto.'

That is the correct spelling of "sister" (may be capitalized before the name of a nun).
