What will happen if a roscore has already been run when I run a launch file? Does the roslaunch override the old roscore?

Nothing spectacular: roslaunch will detect that a roscore instance is already running and use that (instead of starting a new one).

From the roscore wiki page:

NOTE: If you use roslaunch, it will automatically start roscore if it detects that it is not already running.
