Q: apple id disable,ive change my password so many times and still my apple id still disable,i can not purchased any apps on apps store

What steps have you done ? As well as resetting the password you've logged out of the account (tap on your id in Settings > iTunes & App Store on your iPad and then tap 'sign out' on the popup) and then logged back into it with the new password : What to do after you change your Apple ID email address or password - Apple Support ?

I've asked the hosts to remove your image from your screenshot as it includes your account id - it's not a good idea to post your email address on any public forum.

You were able to log back in ok via Settings > iTunes & App Store, it's only when then trying to download something that you have a problem ? What have you tried to see if it fixes it e.g. disconnecting/reconnecting to your network, closing the App Store app via the iPad's taskbar, soft-reset of the iPad ?
