security question

Do you mean that you've forgotten their answers ? If you do then if you have a rescue email address (which is not the same thing as an alternate email address) set up on your account then you can go to https://appleid.apple.com/ and click 'Manage your Apple ID' on the right-hand side of that page and log into your account. Then click on 'Password and Security' on the left-hand side of that page and on the right-hand side you should see an option to send security question reset info to your rescue email address.

If you don't have a rescue email address (you won't be able to add one until you can answer 2 of your questions) then see if this user tip helps : https://discussions.apple.com/docs/DOC-4551

e.g. you can try contacting iTunes Support : http://www.apple.com/support/itunes/contact/ - click on Contact iTunes Store Support on the right-hand side of the page, then Account Management , and then try Apple ID Account Security

or try ringing Apple in your country and ask to talk to the Accounts Security Team : http://support.apple.com/kb/HE57

When they've been reset you can then use the steps half-way down this page to add a rescue email address for potential future use : http://support.apple.com/kb/HT5312

If you mean something else ... ?

How do I make another one or add it

Make another one of what ?

If you mean rescue email address and youknow the answers to your questions then follow steps 1 to 7 half-way down this page : http://support.apple.com/kb/HT5312

If you can't remember your answers then you will need to contact iTunes Support / Apple to get the questions reset before you can add a rescue email address for potential future use
