Installing the tfm and vf fontfiles from CTAN did not help.

after adapting your script to:

\startluacode
mathematics.make_font ( "lucida-math", {
   { name = "lbr.afm", features = "virtualmath", main = true },
   { name = "lbmi.afm", vector = "traditional-mi", skewchar=0x7F },
   { name = "lbms.afm", vector = "traditional-sy", skewchar=0x30, parameters
= true },
   { name = "lbme.afm", vector = "traditional-ex", extension = true },
   { name = "msam10", vector = "traditional-ma" },
   { name = "msbm10", vector = "traditional-mb" },
} )
\stopluacode

ConTeXt found the fonts but gaves:

No success so far...
