He and She are/is, none are/is

I want to get a correct perspective of Native Speakers here at these:

He and She are going out together  OR  He and She is going out together

None of them is capable of making the exact statue  OR  None of them are capable of making the exact statue

Aren't I good ?  OR  Am I not good?

Where is he and she? OR  Where are he and she?

 You and She are identical   OR   You and She is identical 

You or They are going to do it    OR  You or They is going to do it 

 Neither of you are going to see  OR  Neither of you is going to see

 Neither he or she are going to see  OR  Neither he or she is going to see 

Either you or them is coming back OR  Either you or them are coming back

Which ones are grammatical ?

Thanks 

I'm a little confused here, which ones are correct, the ones in blue or the ones in grey ?

another 4 questions, please answer:  are these correct?

Either he or you is telling them

He or you is confronting him 

 Neither they or you are trying hard

 Neither he or you are trying hard

Thanks

Neither you nor he is giving me present
