The Nine Signs of the Prophet of Allah Moses (peace be upon him)

Answer (and Allah is the Granter of success):
The signs are: the staff, the hand, the flood, the locusts, the lice, the frogs, the blood, the years (of drought), and the decrease in fruits/crops.
As for the other signs that occurred at the hand of Moses, they were signs specific to the Children of Israel—such as the splitting of the sea, shading them with clouds, sending down manna and quails, and the rock from which water gushed when Moses struck it with his staff, and so on.
