Presentation\Nop.Web\Models\Common\ContactUsModel.cs
[Required]
        [DataType(DataType.PhoneNumber)]
        [NopResourceDisplayName("ContactUs.Phone")]
        public string Phone { get; set; }


Can anyone help with error.

go to contact us view and from view goto model and let again that is this the correct model that added this property.

this error clearly mention that "Phone" property not exist into ContactUsModel class.
Same name model exist multiple time into project.

I have just made the changes that you have provided here to the latest version of nopcommerce 4.2 and can confirm that it is passing the information correctly.  I have a breakpoint set on the CommonController.ContactUsSend(ContactUsModel, bool) HttpPost method and can confirm that the phone number is passed to that controller method.

The error message suggests that your model does not have the Phone property though.

Assuming you have performed the exact changes to the files mentioned above, then I would perform a clean and rebuild to ensure that those changes to the model have been copied to the bin directory.  Check the Error List/Output windows for any errors and ensure you are not running a previously working build.  I can't see any reason why your changes should not be working.
