Thank you very much for the example. I got it working for the "regular" style-alternative.

I don't know why, but the italic style-alternative do not work. In the log, the font is not even loaded... Do you have an idea of what I'm doing wrong?

The \definefontfamily command is limited to the default alternatives (tf, bf, it, sl, bi, bs ans sc).

Thanks for your answer, what shall I use to define non-default alternatives? 

At the moment your only option is to write your own typescript for the fonts.

\definefontalternative[sb]
\definefontalternative[si]

\starttypescript [sans] [source-sans]
  \definebodyfont [default] [ss]
    [tf=Sans             sa 1,
     it=SansItalic       sa 1,
     sb=SansMedium       sa 1,
     si=SansMediumItalic sa 1,
     bf=SansBold         sa 1,
     bi=SansBoldItalic   sa 1]
\stoptypescript

\starttypescript [sans] [source-sans]
    \definefontsynonym [Sans]             [file:SourceSansPro-Regular.otf]
    \definefontsynonym [SansItalic]       [file:SourceSansPro-It.otf]
    \definefontsynonym [SansMedium]       [file:SourceSansPro-Semibold.otf]
    \definefontsynonym [SansMediumItalic] [file:SourceSansPro-SemiboldIt.otf]
    \definefontsynonym [SansBold]         [file:SourceSansPro-Bold.otf]
    \definefontsynonym [SansBoldItalic]   [file:SourceSansPro-BoldIt.otf]
\stoptypescript

\definetypeface [source] [ss] [sans] [source-sans] [default] [features=default]
\definetypeface [source] [mm] [math] [xits]        [default]

\setupbodyfont[source]

\starttext

Upright {\it Italic} {\sb SemiBold} {\si SemiBoldItalic} {\bf Bold} {\bi BoldItalic}

\stoptext
