When I press Ctrl + Alt + F(1-6), I'm directed to virtual terminal. I've two user account except guest. When I try to login from one of those two users, my system gets hang. So, I was wondering how to restart that virtual console from another virtual console or how to kill all processes in one virtual console from another virtual console.

If you have sufficient privileges, you can use pkill with the -t switch to kill all processes on a particular terminal device e.g. to kill all processes under the Ctrl+Alt+F2 virtual terminal (whose device is /dev/tty2)

sudo pkill -t tty2

See man pkill for additional options

Run in terminal 

ps -ft tty2

Output will be look like: 

UID        PID  PPID  C STIME TTY          TIME CMD
root      1024     1  0 06:52 tty2     00:00:00 /bin/login --     
gulu      3532  1024  0 09:15 tty2     00:00:00 -bash

Here I am going to kill Virtual Console 2 (tty2). Just kill the pid of /bin/login -- with root privilege 

kill -9 <pid>

here, 

kill -9 1024
