As we all know, acquaintances are the people whom we know but do not know well and therefore they are not considered as a friend.
We have a term which can encompass all the people we know, including: all the familiar people including friends, and people that comparing your close ones, you know them less.
As I know, "acquaintace" cannot be used in this sense, because it cannot encapsulate close people to you.
I wonder if there is a term/word/expression which can indicate such a meaning in current English.
