You have to access the counter with \rawcountervalue[<countername>] but in your case you can use a different counter mechanism.
\setvariables[slide][list={1,2,3,6,7,8}]
% \setupbackgrounds[page][background={fond,Auteur,backgraphics,foreground,foregraphics}]
\def\startSlide
{\increment\SlideCounter
\doifinsetelse\SlideCounter{\getvariable{slide}{list}}
{\directsetup{slide:start}}
{\gobbleuntil\stopSlide}}
\def\stopSlide
{\directsetup{slide:stop}}
\startsetups slide:start
\page
\stopsetups
\startsetups slide:stop
\page
\stopsetups
\starttext
\dorecurse{10}
{\startSlide
{\tfd\recurselevel}
\stopSlide}
\stoptext
