I want to create new Apple ID in my phone

You will have have to use one of the existing Apple ID accounts created, and can create no more on that iPhone.

If whatever Bad Idea you're involved with here needs yet more, see: How to create a new Apple ID - Apple Support

Create a new ID (if necessary)on another Apple device/computer and sign into iCloud using the same Apple ID on another Apple device/computer. You should then be able to sign in.
