Please fix my phone I want to create a new apple ID

You can only make 3 apple id’s on one phone, no exceptions. This is for life. If you want to make a new apple id you can do it using a web browser:

https://appleid.apple.com/account

There is nothing wrong with your phone which might need to be fixed to create a new Apple ID. If the iPhone will not cooperate just go online with a regular web browser to https://appleid.apple.com and you should see a link to create a new ID.
