thank you very much for your help.

I am learning day by day how to use Guix.

I understood till now that creating manifests mean several packages in one manifest, like in my music profile: ardour, audacity, audacious, musescore.

You mean `in one profile`? Correct.

When I was opening that profile I used musescore, I had to close it and then open audacity and so on.
It seems to me I can’t open several packages at once.
Or I don’t know how to do it, if possible.

That's weird. What happens if you try to run a second program from the profile while the first one is still running?

Two ways that you can do it:
1) With two terminals:
   1. In the first one run:
      $ source ~/Projekte/Musik/guix-profil/etc/profile;
      $ mscore;
   2. In the the second terminal run:
      $ source ~/Projekte/Musik/guix-profil/etc/profile;
      $ vlc;

2) With one terminal:
      Run the first, (or all commands) in the background, so that the
      shell directly prompts you for the next command:
      $ source ~/Projekte/Musik/guix-profil/etc/profile;
      $ mscore &
      $ vlc &

Now I realised that to create a manifest means one package, only musescore, or only emacs with all its emacs packages.

No, that's not always right. The manifest you posted in this thread contains multiple packages and you created a profile with all those packages.

Then upgrading the manifest/one profile
would not be a problem.

There can be multiple packages be in one profile, created by one manifest, and using this command it should be no problem to update all packages, but keeping musescore at version 3:
>> guix package -m /home/gfp/Projekte/Musik/musik.scm --profile
>> /home/gfp/Projekte/Musik/guix-profil

What would be the difference to have several profiles in my main profile
without haveing guix home,

What do you mean by having several profiles in your main profile?
AFAIK there is no way to put one profile inside another.
Do you mean several packages in one profile?

or to have several profiles in Guix home?

I never used guix home. I cannot answer that.
