Can I change my @iCloud.com Apple ID email?

You cannot rename an email account. As that would basically equate to creating a completely different account.

The name is what identifies the account uniquely.

You can add an alias to your existing iCloud account, and use that instead.

An Alias is a secondary email address tied to an original email account. All email sent to the Alias address arrives at the inbox for the main account, but appears as a different email address.

See the link provided in an earlier reply for how to create an Alias email address on your current iCloud account.

Then is it possible to create and log in with a new icloud and not lose anything from the previous one? or keep them both in the device and just switch whenever?

No. If you create a new account, its an entirely new account, and would have no ties to the previous one and all its purchases.

You can only switch account once very 90 days on a device.

Unless the current name is super offensive to you, or has some other issue you cannot get passed, the easiest and most convenient thing to do, is to just create an Alias and use that for your email communications.
