Combinations are ConTeXt's way to align several pictures (preferrably at same size):

Combinations

\startcombination[x*y] %% x=columns, y=rows
{something}{caption} ...
...
\stopcombination

or using the newer interface:

\startcombination [nx=3, ny=2]  %% 3 columns, 2 rows
  \startcontent something \stopcontent
  \startcaption caption   \stopcaption
  \startcontent something \stopcontent
  \startcaption caption   \stopcaption
  \startcontent something \stopcontent
  \startcaption caption   \stopcaption
  \startcontent something \stopcontent
  \startcaption caption   \stopcaption
  \startcontent something \stopcontent
  \startcaption caption   \stopcaption
  \startcontent something \stopcontent
  \startcaption caption   \stopcaption
\stopcombination

means:

You define, how much figures in columns * rows you'd like to align.

You must provide one "figure something" (e.g. an \externalfigure) and a caption for every "cell".

The sample, from the manual, shows how to define a caption for the whole group and use it as float (see Floating Objects):

\useMPlibrary [dum]  %% sample images

\startplacefigure [title=An example of a combination]
  \startcombination [nx=3, ny=2]
    \startcontent \externalfigure [dummy] \stopcontent
    \startcaption a                       \stopcaption
    \startcontent \externalfigure [dummy] \stopcontent
    \startcaption b                       \stopcaption
    \startcontent \externalfigure [dummy] \stopcontent
    \startcaption c                       \stopcaption
    \startcontent \externalfigure [dummy] \stopcontent
    \startcaption d                       \stopcaption
    \startcontent \externalfigure [dummy] \stopcontent
    \startcaption e                       \stopcaption
    \startcontent \externalfigure [dummy] \stopcontent
    \startcaption f                       \stopcaption
  \stopcombination
\stopplacefigure

Floatcombinations

When combination contain floats, the command \startfloatcombination is used. Here an example using float combinations as well as subfloatnumbering that creates subfigures sharing a mutual figure prefix and an individual subfigure designator (e.g. figure 1a), figure 1b, etc.).

\useMPlibrary [dum]  %% sample images

\startplacefigure [location=none]
  %\startsubfloatnumbering % This does not work!
    \startfloatcombination [nx=2, ny=1]
      \startplacefigure [title=Left,  reference=fig:left]  \externalfigure \stopplacefigure
      \startplacefigure [title=Right, reference=fig:right] \externalfigure \stopplacefigure
    \stopfloatcombination
  %\stopsubfloatnumbering % This does not work!
\stopplacefigure

See \in{figure}[fig:left] and \in{figure}[fig:right].

Setup

There is \setupcombinations command.

Referencing

To reference a subfigure you can provide the subfigure's caption as a second parameter to the \in command.

To reference the subfigure with the caption d you would write:

\in{figure}{d}[fig:combinations]

This would produce something like 'figure 2.4d'. The content of the second parameter simply gets appended to the end of the figure's reference-number, thus the example above would still work even if the caption would be 'd) An awesome subfigure'.
