Answer 1

When you do screen -ls the first number of the screen name is the process id. So if the output is

There is a screen on:
    21605.pts-0.Random-server   (11/12/2017 11:44:15 PM)    (Detached)
1 Socket in /var/run/screen/S-kg.

Then this will kill it:

kill 21605

Notice the number for the kill command is the same as in the screen -ls output.
