Market as a group or separate?

I have the following set of domains and wonder what the group thought would be the best way to sell these…as a group or single?
worldshottestwife.com
worldshottesthusband.com
worldshottestgirlfriend.com
worldshottestboyfriend.com
I can't post to marketplace yet….but when I am able, can you post domains as a set or must everything be singular. Sorry for all the questions, but just want to do it right.
