基本上都对，但是需要注意，第一点：第一句中的单三应该是 she lives，第二点：去她家，在美语中，很少会有说go to her home的，一般说go to her house，如果是初中的话，这两句都可以，但是无论是行文还是口语中，用 go to her house 更符合西方的用词习惯
Do you know where she lives?
I want to go to her house.
此外，在初升高或者高考英语作文中，很多同学会奇怪，为什么我的语法都对，用词都正确，内容也都完整，却得不到满分作文，就在于你犯了go to her home这种语法正确但习惯不对的错误。
Do you know where he lives？
翻译：
Do you know where Cathy lives?
where Cathy lives 是know 的宾语从句。
I want to know where do you live.
Excuse me! Could you please tell me where I can buy medicine?
where does she live?
Do you know which house that he lives {is living} in?
