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...

AMIN(1)                                                       General Commands Manual                                                      AMIN(1)

NAME
amin - notify writers that you are busy SYNOPSIS
amin [-ynesp] command [args...] DESCRIPTION
Amin is used when you don't want to be written while running a command. It runs the command given normally. If your message permissions (see mesg(1)) are off, it does nothing much else. If your messages are on, people writing you with write(1) will be warned that you are running that command and will be given the opportunity to change their minds about writing you. The -n option may be used to turn your messages entirely off for the duration of the execution of command. People writing you will get "Permission denied". The -y option turns your message permissions on for the duration of the execution of the command. The -e may be used after either -n or -y to indicate that the logins listed in the .yeswrite or the .nowrite files respectively are exceptions to the message permissions set. The default is -s which leaves your message permissions in their original state. In any case, after the command is com- plete, your permissions will be restored to the original state. The -p flag causes all telegrams sent to you while the command is running to be saved. They are displayed as soon as the command is com- plete. If used with the -n flag, writes are refused, but telegrams are still saved. If you have designated yourself as a helper, you will still be marked on the finger(1) output as a helper while you are running amin but people doing ``write help'' will not be connected to you, even if you have the helper flag set to ``Y''.
