The answer to “I’m going home” is: Je rentre chez moi.  Why is “chez nous” not acceptable?

In the short quiz, the sentence was  'Nous craignons qu'il  ne change d'avis". The correct answer given was : 'We fear that he would change his mind'. Because of the 'ne', should the answer be " We fear that he would NOT change his mind?  I also want to know whether 'change d'avis' is an expression?     Thanks.

Question is you haven't lived here long?

I answered tu n'as pas habilité ici depuis longtemps as per the explanation leçon un négatif sentence i should use passé composé

But  kwiziq is saying right answer is 

Tu n'habites pas ici depuis longtemps

Please explain

I just did an exercise from a textbook on Passe compose. The exercise requires you write the correct form of the words in brackets.

Q-.Combien de femmes avez-vous (Voir)?

My answer was: Combien de femmes avez-vous vu? 

But the answer given by the textbook was: Combien de femmes avez-vous vues?

Which answer is correct and why because I know passe compose using avoir does not agree with gender. Help with explanation if I am wrong
