Get locale entry.title in other languages
You can use the 'locale' and 'id' attributes in your query to request the same entry in another locale.

{{ entry.title }}&lt;br&gt;
{{ craft.entries.id([entry.id]).locale('nl_nl').first.title }}


Update. If there is any chance that the entry/section is disabled for that locale you can also check it first, like so.

{% set nlEntry = craft.entries.id([entry.id]).locale('nl_nl').first %}
{% if nlEntry %}
    {{ nlEntry.title }}
{% endif %}
