The missing font change occurs between level 5 and 6 when you use the 
correct conversion name as shown below.

The reason for this is the default font size for the sections and the 
fact that \tf doesn't switch to the default font size, i.e. when you use 
\tf after \tfa the a-size remains.

\starttext
\tfa{\tfc 1.}{\tfb 1.}{\tfa 1.}{\tf 1.}{\tfx 1}
\stoptext

This should be: \defineconversion[NE][\NivE]

A better alternative is to create a processor for each conversion.

\defineprocessor [level_3] [style=\tfc]
\defineprocessor [level_4] [style=\tfb]
\defineprocessor [level_5] [style=\tfa]
\defineprocessor [level_6] [style=\tf ]
\defineprocessor [level_7] [style=\tfx]

\defineconversionset
   [mysectionnumbers]
   [n,n,level_3->n,level_4->n,level_5->n,level_6->n,level_7->n]
   [n]
