Unterhut

Polearms

From middle guard lower the point yet further such that it is on the ground in front of you, be it to the left, to the right, or in the middle, and the rear hand is against the side of the body at around lower rib or upper hip height. This is the low guard.

Dagger

This is described in the text as being a right leg forward guard with the dagger being held in front of/by the left thigh, point toward the opponent. This might be a reverse grip or orthodox grip, and could be extrapolated to the right side in the same way.
