Read through the Administrator's Manual - client authentication section.

SELECT * FROM pg_user;
Users exist for the whole database cluster, not just one database.
However you can use client authentication (see below) to limit access to
particular databases.

Yes (unless you specified differently on initdb's command line.)

User authentication is controlled by the file $PGDATA/pg_hba.conf
By default, access is allowed without any check or password to anyone
connecting through the Unix socket; users are trusted to tell the truth
about who they are.
You can set a password with ALTER USER but it won't be used until you
change the authentication policy.

They are in the documentation.
In psql, the command \dS will list them.
