I think you might have missed the part where you can upload multiple images to the image compilation tool in mindar. After the compilation (where all the targets get compiled to one single mind file), it specifically shows the target image numbers (1-indexed). Hence you can use zero-based indexing to specify the targets.

<a-entity mindar-image-target="targetIndex: 0">
   ...
</a-entity>
<a-entity mindar-image-target="targetIndex: 1">
   ...
</a-entity>

Hope this clears your doubt.
