Asking "These are my friends"
If you wanted to specificy your friends in a group of people, would you use the first example below? Or is that not grammatically correct?
Ceux sont mes amis -- These/those are my friends?
Ce sont mes amis -- They are my friends.
Hm, my French is a bit rusty from about 40 years ago, but I think in your first sentence, I'd add a "ci" (if I pointed, from a distance, in the direction of where my friends stood):
"Ceux-ci sont mes amis."
"Ce sont mes amis" looks good to me, too. I'd use this one if the friends stood close by.
But let's wait for more opinions.
