Q:
Living Story Refugee Items
A:
yes
I just helped someone find a compass today as a matter of fact
As kitanas mentioned, you can still find the belt and compass.
The order they are found doesn’t matter, but you can only find each item once.
So if you go to a dirt/snow covered object, and it has an item you’ve already found, it won’t let you dig it up again. You’ll have to go look for another dirt/snow covered object.
As to finding them, go to Diessa Plateau and Wayfarer foothills. ArenaNet releases the items in pairs (one in each zone).
People should be asking in /m where they are every few minutes, or you can ask.
You can also use external websites, like dulfy.net. Here is what they have for the 6 Lost and Found achievement items:

Good luck, hope you find your last 2 items.
