You can use clean() method to do your validation logic in it:

class UserprofileForm(forms.ModelForm):
    class Meta:
        model = Userprofile
        fields=['username1','phonenumber1','username1','phonenumber1']

    def clean(self):
        # do your validation here, such as
        cleaned_data = super(UserprofileForm, self).clean()
        username1 = cleaned_data.get("username1")
        username2 = cleaned_data.get("username2")
        phonenumber1 = cleaned_data.get("phonenumber1")
        phonenumber2 = cleaned_data.get("phonenumber2")
        if (
            ((username1 and not username1.isspace()) and not phonenumber1) or
            ((username2 and not username2.isspace()) and not phonenumber2) or
            ((not username1 or username1.isspace()) and phonenumber1 is not None) or
            ((not username2 or username2.isspace()) and phonenumber2 is not None)
        ):
            raise forms.ValidationError("Name and phone number required.")
        return cleaned_data
