I tried to change my username using command:
sudo usermod -l newusername oldusername
so when I entered it in terminal it showed me:
user 'myusername' is currently used by the process 2553
What does it mean?

You need to change user names in recovery mode, the error message you got I am guessing is because you are logged in and running processes as the user you want to change.
