Fine for everything except Hypo Clearing Agent. That stuff is primarily sodium sulfite and oxidizes easily. It won't change color or give any other indication that it has gone off either, so you'll have no easy way of knowing if it's spoiled. You'll do no direct harm with spoiled HCA, but spoiled HCA is useless as a wash aid. Best to store that in either glass or PET with tight fitting caps, same as you would for a developer.
