The singular form of the plural noun symmetries is symmetry.

yes, in fact it can have 6 rotational symmetries.

Yes, a regular n-gon has n reflectional symmetries and n rotational symmetries. The n reflectional symmetries correspond to the lines of symmetry that can be drawn through each vertex and the midpoint of the opposite side. The n rotational symmetries arise from the ability to rotate the n-gon by multiples of ( \frac{360^\circ}{n} ), returning it to an equivalent position. Thus, both types of symmetry are equal to n.
Parallelograms: 2-fold Square: 4-fold n-fold symmetries refer to rotational symmetries. Consequently, any symmetries about axes that these and other quadrilaterals may have are not relevant to this question.
