3) That is a YES. You have been unlawfully present in the US. You have to pay close attention to the "ORs" and "ANDs" in the sentences. They're asking if you have ever been in the US unlawfully, overstayed a visa, OR violated in any way the terms of a visa. So yes, you have done at least one of those.

4) This one I am not sure. I think you can say YES, because you'll be having a doctor check up before your interview date.

@Demise may be able to give you more information. I also suggest talking to lawyer, just to be sure.

Good luck!
