Yes, being hit by a ton of bricks would still hurt on the moon, but the experience would be somewhat different due to the moon's lower gravity. The moon's gravitational pull is about 1/6th that of Earth's, which means objects weigh significantly less there.
If a ton of bricks were dropped from a height, it would have a lower terminal velocity on the moon due to less air resistance (since the moon has virtually no atmosphere). However, if you were directly impacted by a ton of bricks, assuming they were at rest before the impact, the force would still be substantial enough to cause injury or harm, as the mass is still the same.
In summary, while the mechanics of the fall would be different, the sheer mass of a ton of bricks impacting you would definitely cause serious injury regardless of whether it occurred on the moon or Earth.
