I forgot my apple id and password and now it’s locked it said iphone lock to owner i am the owner and i forgot it is there any way to unlock and put new apple id

Is it possible you are logged into any other Apple devices using that same Apple ID and password? If so just go to the settings in that device, your name at the top, password & security and change the password there. 

Try Account Recovery. Go to iforgot.apple.com to start the process. Please see this article: How to use account recovery when you can’t reset your Apple ID password - Apple Support

If that doesn't work then you'll have to do an activation lock removal. Please see this article, review, and click the link at the bottom to start the process. Keep in mind you'll need proof of purchase for Apple to remove the Apple ID from the device. Once Apple removes the activation lock you'll have to restore it to factory settings. See the following articles:

Tell them to check their web browser autofill entries, the Keychain, and other records, or use Apple's iForgot service, or contact their Account Security team, or if you're the unit's original owner, click here and submit an unlock request.
