1st is like said above an item wich you can sell for 10,000 zenni,
2nd is a coupon wich you can enchant any weapon or sub weapon to +10, the enchantment lasts for 7 days, then it reverts to 0 again, ( Note: you cannot enchant a weapon with +4 etc )
The Blue one is armor upgrade up lv 6, the pink one weapon upgrader up lv 6, the black one is a weapon downgrade, the coins are called event coins, use it using 5 you can exchange it for a random price from the "Event" machine.

The black one is to downgrade armor or weapon (Forgot which is which). The 8 yellow coins are for the event wagu...Right click them
The red stone is the weapon upgrade stone (U6 means for gear lvl 6 and under), the blue is the armour upgrade stone, the black is the downgrade stone, the coin is for the event wagu machine (5 coins = 1 roll on the machine).
