The F0* codes are internal to context/luatex and are font specific (if
at some point you decided to use another font, or updated version of the
same font, you will be getting completely different glyphs if anything at
all).

You can use glyph names which are a bit more portable:

\setupbodyfont[cambria]

\starttext
\fontchar{summation}
\fontchar{summation.vsize1}
\fontchar{summation.vsize2}
\fontchar{summation.vsize3}
\fontchar{summation.vsize4}
\stoptext

 Khaled
