Use the infont operator.  That info is a bit hidden in “2.10 Analyzing
pictures” of the MetaFun manual.

\starttext

\startMPcode
  for i=0 upto 3 :
      for j=0 upto 3 :
          draw unitsquare scaled 4cm shifted (4*i*cm,4*j*cm) ;
      endfor ;
  endfor ;
  for i=0 upto 4 :
      for j=0 upto 4 :
          label.llft(
              char(i*5+j+ASCII "A") infont "SerifBold*default",
              (4*i*cm,4*j*cm)
              ) withcolor white randomized (1,1,1) ;
      endfor ;
  endfor ;
\stopMPcode

\stoptext
