Yes.  Generally, doing yum update or yum upgrade will pick up new point
releases as they become available.  *Sometimes* you need to do something
special (the 5.2 to 5.3 update required an upgrade of glibc on its own
before the main update -- this was in the update announcement).

Fedora does not have 'point releases'.  One does a 'fresh' re-install
every 6 months to a year (or something like that).  CentOS (like RHEL
itself) has long term support for the major version number (like 7
years), with regular updates (security and bug fixes) and point
upgrades (like every 6 months or so).
