"nous nous sommes fait faire les ongles" 

Why is "fait" not "faites" that multiple females had their nails done?

Ma soeur n'aime personne = My sister likes nobody. 

Can't this also mean My sister loves nobody, or how do you express the idea of loving someone/no-one?

Please explain when to use tout and when to use tous. 

I have great difficulty in deciding whether to use l'imperfait or parfait in translations and am surprised to see that both are acceptable in the sentence 'He wrote beautiful lyrics'. The imperfect is the preferred translation but the perfect is given as an alternative translation.

Allo! I'm wondering if you put the determinant only if there isn't an adjective? So if I say "il est policier", there is no determinant, and if I say "il est un policier courageux" I do? Thank you!

In the article we mentioned answering simple questions with "ni l'un ni l'autre" like: 

Quel parfum tu veux ? Fraise ou vanille? - Ni l'un ni l'autre. 

The "ni l'un ni l'autre" is used to replace "parfum", which is the object of the verb. Are there any instances where ni l'un ni l'autre can be used as a direct object or an indirect object in a full sentence? Thanks!

Im wondering what the d represents in d'être. Also, to 'be late' is it always 'metre en retard' or can I say "je suis en retard"

Merci!
