The first and the seccond idk.
The other ones are quests items (right click on them). The last one is a list for craft.
First one is for UD1 to build a short cut, use it in the room with the 3 bridges(before you run down the stairs, with the alarm trigger). Second one
is in UD1 too, but also in Red Pants dungeon 1(lvl 30 Dungeon). Dont know what do do with it in UD1, but in the lvl 30 Dungeon you can blow up doors.
