We don't need THEM/IT?

I was flying on Singapore airlines and they are knows for their services such as offering hot towels and juice. As usual they offered me and my friend hot towels and later juice which neither of us needed. So I said:

Towel

1)We don't need THEM/IT? - Since I was talking about more than one person, should it be 'them' or 'it'?

Juice- Air hostess asked juice or beer:

2) We'll take Juice/Juices?- Again two people, juice or juices?
