Others who received medals were Private John Kavai, Private Kefa Chagira, and Private Ezekiel Nyanjom Anyange.
King and Queen have each laid a wreath at the memorial.
Yesterday, the king addressed the atrocities committed by the colonial government during a banquet at the State House.
He termed the atrocities against Kenyan freedom fighters as "abhorrent and unjustifiable".
The king said he aimed to gain a deeper understanding of the colonial government's wrongs.
"In coming back to Kenya, it matters greatly to me that I deepen my understanding of some of these wrongs, and that I meet some of those whose lives and communities were so grievously affected. None of this can change the past but by addressing our history with honesty and openness, we can, perhaps, demonstrate the strength of our friendship today," he said, championing greater bonds between the two nations.
