I think the last two will be Jack and Danny. Helen really likes Jade. They all seem to like Showbiz, Nick and Joel. I know Marc and Cristian fell out, but they have since made up, and if Marc is thinking tactically then he won't put up Cristian as despite their fallout, he's the one he's closest to in the house. Same with Sam...Marc will need to keep people on his side. Jack I think is an obvious choice. Nikki doesn't like Danny and Helen doesn't seem keen on him either. Also, Harry, Chloe, Jack and Danny ensures that there's a mixture of people they don't and also includes two members of the group that they want to break up (Chloe and Danny).
