Can Chinchillas eat these treats?

I found a new Chinchilla snack provider, very affordable prices too! Although some of the ingredients they sell I haven't heard of before but claim to be edible for Chinchillas and/or Rabbits -

Akebia (Chocolate Vine)
Maypop (fruit and vine) - This is a passionflower I think
Dried Okra pods
Jerusalem Artichoke (flower and stem/twigs)
Honeysuckle vine

Does anyone know if these are safe for Chinchillas?
