How to label points on a plot, when data is imported from a matrix?

I have a code that outputs a number of graphs. At each data point I wish to place next to it a label that says n=1, ...., n=6, corresponding to each data point on the graph. Here is the code I have:

D= load('Convergence.csv');

A=D(:,1);
B=D(:,2);

figure(1);
plot(A,B,'-O','LineWidth',3,'MarkerSize',10,'MarkerFaceColor','[0.9100    0.4100    0.1700]');
xlabel ('Number of Cells','LineWidth',3);

ylabel('Velocity [m/s]')
grid

C=D(:,3);

figure(2);
plot(A,C,'-O','LineWidth',3,'MarkerSize',8,'MarkerFaceColor','[0.9100    0.4100    0.1700]');
xlabel('Number of Cells');
ylabel('Velocity [m/s]');

grid

d=D(:,4);

figure(3);
plot(A,d,'-O','LineWidth',3,'MarkerSize',10,'MarkerFaceColor','[0.9100    0.4100    0.1700]');
xlabel('Number of Cells');
ylabel('Velocity [m/s]');
grid

E=D(:,5);

figure(4);
plot(A,E,'-O','LineWidth',3,'MarkerSize',10,'MarkerFaceColor','[0.9100    0.4100    0.1700]');
xlabel('Number of Cells');
ylabel('Surface Average Pressure Coefficient');
grid

F=D(:,5);

figure(4);
plot(A,F,'-O','LineWidth',3,'MarkerSize',10,'MarkerFaceColor','[0.9100    0.4100    0.1700]');
xlabel('Number of Cells');
ylabel('Mass Flow Rate [kg/s]');
grid
