Well, sometimes, sometimes not. Depends on the output and the input.
Everything depends.

Yes, many.

> 2) so manufacturers use Xformers to colour the sound?

Sometimes, yes, intentionally. Other times because it's the best of
the choices for the given applicaiton. Still other times, it's the
cheapest solution that will work (with little concern for sound
quality).

> 3) What coloured sound means? Distorsion?

Yes.

> 4) do Xformers make the sound bigger but innatural?

Some people attach the descriptor of "bigger sound" to something with
a transformer. But that may or may not be because of the transformer.
More low frequency distortion is often perceived as "bigger" because
harmonics that are in a range that you can hear and that aren't
shrieky and piercing are added to the original signal. That could be
construed at "big."

> What about interstage transformers?

Almost nobody uses them in audio any more, but they were a good
solution when going between stages when design was based around tubes.
