Just looking for the criteria which I would use to say if these groups are cyclic.

Like a short proof? for (i), (ii), (iii), (iv) (v)

Thank you.

A group is cyclic if there exists a single element in the group which generates the entire group. Your first group only has 27 elements, is there an element in there which generates the entire group?
