I.
So in the end I figured out how to get all the images I need to track in one index.xml-file: You see how it should like to work in the first pictures,it's for very picture the same procedur. Just make sure it all has his own objectID and KoordinatsystemID to make it work.
II.
For the code of the XML-Tracking file, I just did like before and export it from the Metaio Creator as AREL Package for each picture and assemble all files in one js-file and one index.xml with the help of the programm : WinMerge:

It helps you to compare your code. All yellow marked things are different and all gray parts doesn't exist in one of teh compared codes.so you new what is the new one and can copy it to your collectingfile.
