On a Scale of 1-10. Tell me how hard it should be to rank these 9 Websites! (Results Provided).

Please let me know how hard it will be to rank each of these sites from a scale of 1-10. Domains are the EXACT SAME keyword searches and all .coms. All are running Wordpress, and are about 2 months old. All have been indexed on Google so far with about 3-4 category pages each and little to no content.. About ready to add content and start the SEO process but want your thoughts. Remember these are 9 websites, all different domains, also to not confused anyone, #'s are just so we can figure out which domains.. (Not my rating)

UPDATE: More information on Competition.

Anyways, all of the competing sites have 100-400 backlinks at most (95% are low ranking sites just who is, stat sites and business directories, etc.) Very weak backlinks and they have NO SEO link building or anything of that nature.. Most of the domains are anywhere from 2-6 years old. They all have some on-page SEO but it's very poor and doesn't really look like anything's been done. Most of the sites are anywhere from 40-100 pages with 80% of the pages being inner product pages. Very little real content, just a lot of product specs and scrambled words on the pages.
