Hi @bpeddapudi, you can try below code, it will list all available localized values for given tag. To get more control you can move your code into Sling model.
<ul>
<li data-sly-repeat.tag="${relatedTags.iterator}">
${tag.title} <br />
// get localized title
<sly data-sly-list="${tag.localizedTitles.entrySet}">
${item.value} <br />
</sly>
</li>
</ul>
