Quick test proves the editor doesn't like having a 'rel' attribute on an img tag in fckstyles.xml. The style just doesn't show up in the drop-drop list, as the screenshot shows.
However I tried changing the tag name from 'img' to 'a' and the style then appeared fine, with the rel attirubte.
For Lightbox to work properly, you should be setting 'rel' on the <a>, not the <img> - so it should be entirely possible to use Lightbox here.
Please refer to the Lightbox docs for more information.
