Define a float type `rightfigure` that inherits from `figure`;

then setup that float's caption with \setupcaption[rightfigure][...=...]. Like so:

\definefloat[rightfigure][rightfigure][figure]

\setupcaption[rightfigure][location=right]

\starttext
\placefigure{caption 1}{\framed{figure 1}}
\placerightfigure{caption 2}{\framed{figure 2}}
\placefigure{caption 3}{\framed{figure 3}}
\stoptext

Example stolen from:

On what wiki pages did you look? Perhaps you could add a sentence

'For adjusting the captions and their location, see {{cmd|setupcaption}}.' so that future users will be led to the page they need.

Cheers,
