which unix command should i use?  

chsec?  chuser?

Can anyone provide an example of a command that changes the maxage, maxexpired, maxrepeats, minage, minalpha of all the users on AIX?

AFAIK there is no command which can change all users.
But you might use awk or perl to do it. For example to set maxage to 123:

  awk -F: 'printf "%s:%s:%s:%s:%s:%s:%s:%s:%s\n", $1,$2,$3,$4,"123",$6,$7,$8,$9}' /etc/shadow

could you explain how the above awk line is constructed?
and I don't see /etc/shadow/  on the AIX system I am running...

I thought that the command chsec could change the default setting which are shared by all users.

For example, by the manual of chsec

To allow logins from 8:00 a.m. until 5:00 p.m. for all users, enter:

chsec -f /etc/security/user -s default -alogintimes=:0900-1700

  This script will change all your common users. ( not system default users as
root,lpd and daemon ).
Modify the parameters as you wish, save the script and run it.

for i in `lsuser ALL|cut -f1 -d' ' |grep -vE "root|lpd|daemon"`
echo "Changing User:" $i
chuser minage=0 $i
chuser maxage=0 $i
chuser maxexpired=0 $i
chuser maxrepeats=8 $i
chuser minalpha=0  $i
echo "End Of Changes"

If there are other users you want not to be modified, just include it in the
grep -vE parameter.
If you want all user to be modified, including system default users, just
change the script by removing the |grep -vE
