Can I change my Apple ID

Depends on what you mean by change exactly.

You can change the email address you use as your Apple ID if it's a third party email address. Click here ➡️ Change the email you use as your Apple ID - Apple Support

You can change to a completely different Apple ID, that has no connection with the current one. Click here ➡️ How to create a new Apple ID - Apple Support

You cannot change the email address for your Apple ID if it's an iCloud email address however.
