Question

Can I use these interchangeably?

You've turned into a really beautiful girl.
You've grown into such a beautiful girl.

Answer

I have zero trust in him, is a current and popular way of saying that.  It is good if you emphasise the zero when speaking it.

Answer

If you say you’ve turned into such a beautiful girl, it kind of means that something else influenced that or that it may have happened suddenly.  You’ve grown into such a beautiful girl is when you’ve watched the girl grow up and can see how she’s developed and grown more beautiful.

Answer

Both are understandable but I would say grown is the correct choice of word here
