Among not yet frum people the traiditional blessing of haMakom is not used but rather people wish each other ' a long life or chayim aruchim' whilst this term is reserved for avelimg. Is there any issur in wishing 'long life' to other family members of the deceased but not the close members sitting shiva? Does one have to distinguish between what he wishes an avel and someone just close

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, see the FAQ.
HaRav Tzvi Pesach Frank Zatzal says that you may say Chaim Aruchim to the mourners and it is not considered like a greeting.
