Who was hunting who in the 4th Phase of the 287th Hunter Exam?


In the 4th phase of hunter exams, applicants have to hunt each other, we know
some huntings of the applicants:

> ? -> kurapika (#404) -> Tonpa (#16) -> Leorio (#403) -> Ponzu (#246) ->
> Bourbon (#103) -> ?
>
> Gon (#405) -> Hisoka (#44) -> Geretta (#384) -> Gon (#405)
>
> ? -> Imori (#198) -> Killua (#99) -> Umori (#199) -> ?
>
> ? -> Hanzo (#294) -> Amori (#197) -> ?
>
> ? -> Siper (#80) -> Illumi (#301) -> Goz (#371) -> ?
>
> ? -> Pokkle (#53) -> Kyu (#105) -> ?
>
> ? -> Sommy (#118) -> Bodoro (#191) -> Ryu (#34) -> ?

But there are some others that I couldn't find. Does anyone know who are the
missing huntings that are represented with an interrogation mark?
