The first one is the defense warships, designed to protect our Solar System from the hostile aliens.
The third and fourth pictures are your typical Varkian elite cities, only difference is that its for the highest ranking of the highest rankings.

Unlike most of 'elitest of the elitist' where they do have Varkian members producing offsprings with humans, the elite where Senran came from didn't have one yet, making them subject to mocking from other species, until Xen came by.
The fifth image is indigenous Varkian village, where Senran's famiky visits to support there.
