You can use the commalist environment:

\starttext

\startprocesscommalist[One,Two,Three,Four]
     Person Number \currentcommalistitem\par
\stopprocesscommalist

\blank

\defineexpandable\NameList{One,Two,Three,Four}

\startprocesscommacommand[\NameList]
     Person Number \currentcommalistitem\par
\stopprocesscommacommand

\stoptext


Another way is to use the database module:

\usemodule[database]

\starttext

\defineseparatedlist
   [namelist]
   [command=\NameEntry]

\starttexdefinition unexpanded NameEntry #1
     Person Number #1\par
\stoptexdefinition

\startseparatedlist[namelist]
One
Two
Three
Four
\stopseparatedlist

\stoptext
