My Apple Account is disabled

There are multiple reasons for an account to be disabled, and the advice provided by SravanKrA does not correspond to the message you report. You also make no mention of Activation Lock. This is the information you need:

If a message says 'Your Media & Purchases account has been disabled' - Apple Support or "You cannot login because your account has been locked”, this is not something anybody on this forum can resolve for you. You might be able to request reactivation by tapping Continue right from the alert. If that does not work, tap or click on this link and choose the self help method, or a contact option ➞ https://getsupport.apple.com/?caller=kbase&PGF=PGF63005&category_id=SC0245&symptom_id=23362 .

or for additional telephone contacts refer to: Contact Apple for support and service - Apple Support

If you are not the owner and do not have the Apple ID and Password then there is no way that you can get into this iPhone unless the original owner shares the Apple ID and password with you. If you are lucky you can get into this iPhone if they (owner) accidentally remove the device from their Apple ID.
