"The other languages are new, derived and possibly closely related to Lisp." Scheme's first specification was in the 1970s some time [1]. From the perspective of 2022, that is not much younger than the original Lisp.

I think there are people with more and less strict definitions of what can be called a Lisp family language. I believe I have seen one person who had a definition such that nothing but Common Lisp was a Lisp, not even Scheme. I don't recall why, probably because their reasons did not make much sense to me.

IMHO, I consider Common Lisp, Scheme, Clojure, Emacs Lisp, Autolisp, and a few others I'm forgetting about now a Lisp. I prefer some over others, but I don't kick them out of my Lisp club because they have features I prefer less.

The survey answers to Q12 "How important have each of these aspects of Clojure, ClojureScript, or ClojureCLR been to you and your projects?" on the 2020 Clojure Survey results give some summary answers for several features of those languages, how important the people answering the survey finds them to be. https://www.surveymonkey.com/results/SM-CDBF7CYT7/
