[General] warm hello

[atabitaraf]

When I want to say good bye to someone, if I know their friends, I would say, "Send my warm hello to your ...brother/fella/etc..."
Is it wrong or I can say that?

A: Good bye atabit!
ata: Good bye dear A, by the way how is your sister B? Please send my hello to her.

Say hi to your sister for me!
Give my best to your brother.
Say hello to John from me.

 

[atabitaraf]

Say hi to your sister for me!
Give my best to your brother.
Say hello to John from me.

And when he goes to his sister/brother/John, he will say: 'atabit said hi to you.' / 'atabit gave his best to you.' / 'atabit said hello to you.' / or something else is more usual?

We would normally say "By the way, atabit says hi!"
