Yes, your example works, but you can't put a figure (float) inside a
multicol, so:

\begin{multicols}{2}
 Stuff in 
  \begin{figure}\fbox{figure here}\caption{fig cap}\end{figure}
 \columnbreak
 Two columns
\end{multicols}

generates the warning:

Package multicol Warning: Floats and marginpars not allowed inside
`multicols' environment!.

This is a documented "feature" of multicols.

Best wishes
