All the plants you listed have to be planted into the substrate. To stop your loaches from digging them up you could try placing rocks around them, although I've never heard of loaches posing as a problem with plants.
If you want plants that will attatch itself to bogwood then try Java fern, Anubias, African fern and mosses.
WARNING: The fountain plant you ordered is probably not an Aquarium plant but a terrarium plant. If it is grass like with light and pale green leaves then it will die after a few weeks into your aquarium.
