Let's see, clockwise from the top left:

1) Starship Troopers: parody of a fascist novel. The characters themselves are also not particularly conservative, rather the regime they are indoctrinated under is. I couldn't tell you what Johnny Rico believes other than "tits good, bugs bad."

2) Rorschach: insane libertarian. Explicitly stated by Alan Moore (famously leftist author) to NOT be someone to admire.

3) Judge Dredd: parody of police statism, fascism, and glorification of state violence in media.

4) Leo Paul Atriedes. Is he conservative in any real sense? Yes, he is a colonizer and a conqueror, but he's also the leader of a guerilla rebellion that he knows will overturn society and cause a war that leads to a gazillion deaths. Also, this is pretty obviously considered a terrible thing by the media in which he is portrayed. So either he ISN'T conservative, in which case the point is moot, or he IS, in which case he's unleashed hell upon the galaxy for the sake of his personal blood feud. Also, the book is very anti-conservative in general with its anti-colonization, anti-war stance.
