Modal windows - how to make it work when you need three different modal windows

Hi,
I have a subpage references where 3 projects are listed and I want three CTA to connect me to three different modal windows. It works with the first one - Quartierstrom. I do not know how correctly connect the other two.
Here is a link to my project.
