  DrawGrid1.Canvas.TextOut(Rect.Left, Rest.Top, 'you strings);

Much cleaner

Procedure TForm1.DrawGrid1DrawCell(Sender: TObject; ACol, ARow : Integer: Rect: TRect; State: TDrawState);
Begin
  DrawGrid1.Canvas.TextOut(Rect.Left, Rect.Top, 'your string ');
End;

Test the ARow and ACol:
procedure TForm1.DrawGrid1DrawCell(Sender: TObject; ACol, ARow: Integer;
  Rect: TRect; State: TGridDrawState);
begin
  if (ARow = 3) and (ACol = 4) then
    begin
      DrawGrid1.Canvas.FillRect(Rect);
      DrawGrid1.Canvas.TextOut(Rect.Left + 2, Rect.Top + 2, ' my text');
    end;
end;

ok
  DrawGrid1.Col := 3;
  DrawGrid1.Row := 0;
  lx := DrawGrid1.row ;
  dy := DrawGrid1.Col ;
  DrawGrid1.Canvas.TextOut(lx,dy,'colum name');
This set name in colum 0......

How can I put name in colum 1 to 4.........

Is this what you mean:
var
  col,row:integer;
begin
  for col := 0 to DrawGrid1.ColCount-1 do
    for row:= 0 to DrawGrid1.RowCount-1 do
      DrawGrid1.Canvas.TextOut(DrawGrid1.CellRect(col,row).Left+3,DrawGrid1.CellRect(col,row).Top+3,'colum name');
//...

Then it becomes as follows:
DrawGrid1.Canvas.TextOut(DrawGrid1.CellRect(0,0).Left+3,DrawGrid1.CellRect(0,0).Top+3, 'Name');
DrawGrid1.Canvas.TextOut(DrawGrid1.CellRect(1,0).Left+3,DrawGrid1.CellRect(1,0).Top+3, 'Home');
DrawGrid1.Canvas.TextOut(DrawGrid1.CellRect(2,0).Left+3,DrawGrid1.CellRect(2,0).Top+3, 'Country');

You need to be reading the data from somewhere, Declare an array to hold the column data eg
const
  CHeader: array[0..2] of string = ('Name', 'Home', 'Country');


However for what you are trying to do, you are better off using a TClientDataset and TDBGrid and you dont have to worry about drawing data manually
const 
  CHeader: array[0..2] of string = ('Name', 'Home', 'Country');

procedure TForm1.DrawGrid1DrawCell(Sender: TObject; ACol, ARow: Integer;
  Rect: TRect; State: TGridDrawState);
begin
  if ARow = 0 then
  begin
    DrawGrid1.Canvas.TextOut(Rect.Left + 2, Rect.Top + 2, CHeader[ACol]);
  end;
end;
