"Guys" for...

If there is a group of people and all of them are female, can we call them guys?
If there is a group of people and all of them are male, can we call them guys?
If there is a group of people and they are male and female, half and half can we call them guys?
If there is a group of people and most of them are girls, can we call them guys?
If there is a group of people and we don't know the genre exactly, can we call them guys as well?

If there is a group of old people female and male, can we call them guys?

 

How can I use the term "guys" properly without discriminate and being sexist?
Are there other terms for these cases?

 

Thanks everybody! :)

I wanna talk about philosophy today.

After long time I realized there are two kind of persons in this world:

 

The one who farts when no one is watching him and is worry about it.

and

The one who farts in front of the people and doesn't even care about it.

 

Believe or not, this issue tells a lot.
