Do you also want equation numbers? If so, then that is not supported by
ConTeXt at the moment. If you do not want equation numbers, you can use

\startformula \startalign[n=1]
\NC equation 1 \NR
\NC equation 2 \NR
\NC \startmatrix[left={\left.}, right={\right\}}, n=1, align=middle]
\NC equation 3 \NR
\NC equation 4 \NR
\NC equation 5 \NR
\stopmatrix
some text here           \NR
\NC equation 6 \NR
\stopalign \stopformula

With LaTeX, you can also use mathtools package, which is much easier to
use.

Math support will be reworked at some stage in MkIV.
