How can I code the Fixed Row in Bold (font) style whereas Normal Rows in Normal 
style for TStringGrid component?

Answer:

You need to handle the OnDrawCell event.
1   
2   procedure TForm1.StringGrid1DrawCell(Sender: TObject; ACol, ARow: Integer;
3     Rect: TRect; State: TGridDrawState);
4   var
5     Fmt: integer;
6   begin
7     StringGrid1.Canvas.FillRect(Rect);
8     {set bold for fixed cells, also set alignment}
9     if gdFixed in State then
10    begin
11      StringGrid1.Canvas.Font.Style := [fsBold];
12      Fmt := DT_SINGLELINE or DT_VCENTER or DT_CENTER;
13    end
14    else
15      Fmt := DT_SINGLELINE or DT_VCENTER or DT_LEFT;
16    DrawText(StringGrid1.Canvas.Handle, PChar(StringGrid1.Cells[ACol, ARow]), -1, 
17  Rect,
18      Fmt);
19  end;
