the first 5 items are trash the other 2 are used to craft quest items or specific items needed to complete a quest hope this helps(not 100% sure on the blue one but the green one is used for quest item crafting)

The first 4 items are repeatable quest items. Feel free to ditch them if you dont want to carry them around, the repeats only give pots, hardly any experience. (if any at all)
The Yellow and Blue medals are repeatable items from the first Special Mission (1-s, tower defense). Both quests are in the first area and give a box as reward. The one you need 3 blue medals for can give you dungeon talismans. It's one of the very few non-cashing methods to get them, so definitely hold on to em.
The last DNA-like item is a crafting item. It drops pretty much everywhere but you shouldn't get rid of it unless you'll never craft anything (which I obviously wouldn't advise)
