An excellent discussion of existentialist philosophy, written for the general public, is in William Barrett's, Irrational Man (1958).
In the U.S.A., the book is widely available in libraries, in new-book stores, and in major used-book stores. There are 6 general characteristics of existentialism. These characteristics include existence before essence, reason is unable to deal with the depths of life, alienation, fear and trembling or anxiety, the encounter with nothingness, and freedom.
existentialism is a freedom of choice
Existentialism is a philosophy and postmodernism was an art form/movement
Existentialism and realism share a common element in that the "self" is a major focus
Atheists have friends like anyone else; existentialism is irrelevant.
It does no such thing ! You may want to read about philosophy to learn what existentialism is.
yes
Existentialist epistemology is, like most existentialism, based on personal choice - i.e. a choice to believe.

Post-existentialism is a philosophical movement that emerged in the mid-20th century as a response to existentialism. It criticizes existentialism's focus on individual freedom and subjective experience, often emphasizing the interconnectedness of individuals within society and questioning the limitations of individual agency. Post-existentialist thinkers may explore themes such as power dynamics, social structures, and the influence of language on human experience.
As far as I am concerned existentialism plays no part.
The Existentialism period was from the late 1930's to the late 1950's, roughly. Hope this helped :)
