i have a company that has different Branches. my question is can a zonedirector manage all these Access points at are on these different other locations?
Yes, assuming you have realizable L3 connectivity between the sites you can manage them with a central ZD (preferably a ZD high availability pair.) Note that if the link is severed, pre-existing clients on the remote APs will continue to function but new authentications will fail until site-site connectivity is restored, unless you have autonomous WLANS set up.
You can set up autonomous mode with anything after 9.8. In Autonomous mode, you can only use WPA, or WEP. You cannot do any radius or 802.1x authentication.
