Of course.<br>
What other possibility is there?<br>

I'm not sure what you mean by 'what principle'. Each one of them is an upload of you, that has changed in some way. Each one is no different to if you had remained biological and made the same changes (assuming the suggested changes are possible in a biological person).<br>
