Please Help with Kali Linux

I need screenshots of this commands

On your remote Kali host, I want you to create a security group called cnslab and also three users: Mario, Luigi, and Yoshi. Their names and usernames should match with a password CNS378418! for each. I then want you to add all three users to the cnslab group. Provide a screenshot of the group on Kali showing all three users added to the group. Lets create some directories and permissions In the root directory of the Kali server, create a directory called cnskali and a file within that directory called cnskali.txt. Now I want you to give that directory and that file the following permissions: I want the owner of the cnskali directory to be Yoshi and the group to be cnslab. With Yoshi having read, write, and execute permissions, cnslab having read and write. For the cnskali.txt file, I want Mario to be the owner and Mario to be the group. With the Mario user and group having read, write, and execute permissions and everyone else having read.
