Is possible to concatenate a String already existing in strings.xml with the current one.
That is: If I have
<string name="hello">hello</string>
and I want to create a new string with the format "Your android says "+hello

I am afraid that is not possible in strings.xml.
What you can do is create the final string programmatically using getString:
String outStr = getString(R.string.your_android_says) +
" " + getString(R.string.hello);

Not sure if this is what you want:
String s = "Your android says" + getResources().getString(R.id.name);
What you could also do it like:
<string name="hello">%s hello</string>
String androidsays = "Your android says";
String s = getString(R.id.name, androidsays);

how if %s has more than 2 ?
you can create any number of altered string , but bounded upto runTime memory only . you can't store persistently this new string like usually you do through values/string.xml .
example String newString = "something" + getResources().getString(id);
sharedPreferences in the way you can achieve this . store newly generated string into sharedpreferences and access later .

If you want to do so without having to add any Java/Kotlin code, you could use this small library I've created: https://github.com/LikeTheSalad/android-stem
It allows you to do something like this:
<string name="app_name">world</string>
<string name="welcome_message">hello ${app_name}</string>
And then the library does this at build time:
<!-- Auto generated during compilation -->
<string name="welcome_message">hello world</string>
