now I am stuck with making the passwords be 16 characters long and ensuring that admin has general sudo access.
Once solved the above remark I made
You can start dealing with this 2 tasks, the first we can't really help we don't know your platform, very likely linux but I am no linux specialist, all I can say is to look at you course again for clues, as what is asked will not be found in /etc/passwd or shadow file... You should have something dealing with PAM e.g. in Debian and debian based, password policies are defined in
/etc/pam.d/common-password file

ensuring that admin has general sudo access
is sudo related, and so what you need to check/add/modify in the sudoers file using
visudo, very important to use that and no other editor as it will check that there is no syntax error which would corrupt the sudoers file, I understand admin should have same as root...
