afaik cambria has no bold font (although it has the unicode bold 
alphabet etc)

iwona and antykwa have four variants of boldness

no relationship ... they are used in some of the math setups (like latin 
modern) but are of no use for (say) cambria

bold math italic is an alphabet and cambria has it

the virtual variants don't seem to have them so I've added fallbacks for 
them, so in the upcoming beta all these should show up

\starttext
     \switchtobodyfont[iwona-light]  $ \mathgreekitalic {\alpha} {\bf 
\alpha} {\bi \alpha} {\char"1D736} $ \par
     \switchtobodyfont[iwona-light]  $ \mathgreekupright {\alpha} {\bf 
\alpha} {\bi \alpha} {\char"1D736} $ \par

     \switchtobodyfont[iwona]        $ \mathgreekitalic {\alpha} {\bf 
\alpha} {\bi \alpha} {\char"1D736} $ \par
     \switchtobodyfont[iwona]        $ \mathgreekupright {\alpha} {\bf

     \switchtobodyfont[iwona-medium] $ \mathgreekitalic {\alpha} {\bf

     \switchtobodyfont[iwona-medium] $ \mathgreekupright {\alpha} {\bf

     \switchtobodyfont[iwona-heavy]  $ \mathgreekupright {\alpha} {\bf

     \switchtobodyfont[cambria]      $ \mathgreekitalic {\alpha} {\bf

     \switchtobodyfont[cambria]      $ \mathgreekupright {\alpha} {\bf

\stoptext
