IMO:
Yes, if he had both hands free, the weapons are in easy reach, and he took no other action that prevented him from making a full attack in that round.
So, he could drop a weapon, move 5 feet, draw two daggers and throw them.
But he could not throw them both if he moved more than 5 feet, nor could he throw them both if he had performed some other Move Equivalent action like sheathing a weapon.
