How to create a legend with multiple plots?

The following code is what I used to plot my graphs

h1=plot(exp(Xs),exp(Yest),'-b','LineWidth',2);
 hold on
 h2=plot(exp(Xs),exp(YCI95s),'--r','LineWidth',2);
 h3=plot(exp(Xs),exp(YCI90s),':c','LineWidth',2);
 h4=plot(exp(Xs),exp(YCI75s),'--g','LineWidth',2);
 h5=plot(exp(Xs),exp(YCI50s),':m','LineWidth',2);
h6= scatter(exp(data1.logAge),exp(data1.logRate),'x','k');

I was wondering if there is a way to make one legend for each plot. h2, h3, h4,h5, are confidence interval bands.

h(1) = plot(1:5, rand(1,5)+1)
hold on
h(2) = plot(1:5, rand(1,5)+2)
legend('alpha','bravo')

This is one legend for the different lines. I think it is not clear what you want. Is this it?

This is my plot I have 2 lines with the same color, I'm wondering how to create a legend representing each line once.

How can I insert legends for every curves for any variable and how can I insert greekk letters in legends..... The MATLAb code is

fid1=fopen('Zeta.txt','w');

fprintf(fid1, ' Gr \t M \t Q \r\n');

fprintf(fid1,'---------------------------------------------------\r\n');

Gr(1)=5;

M(1)=5;

for i= 1:4

for j=1:1001

a(j)=M(j);

R = 2.500;

alpha = pi/4;

K = 0.41;

x1 = M(j)*M(j);

x2 = sin(alpha);

x3 = Gr(i)*x2;

x4 = x1*R;

x5 = x1*x4;

x6 = x3/x4;

x7 = x3/x5;

x8 = 2/x1;

x9 = 1 + x8;

x10 = x9*x1;

x11 = exp(M(j));

x12 = exp(-M(j));

x13 = x11 + x12;

x14 = x11 - x12;

x15 = x13/2;

x16 = x14/2;

x17 = x13 - 2;

x18 = M(j)*x14;

x19 = x17/x18;

x20 = x16/M(j);

x21 = x10*x15;

x22 = x21 - 2;

x23 = x22*x19;

x24 = x7*x23;

x25 = x9*x20;

x26 = x6*x25;

x27 = R*K;

x28 = 2*x1;

x29 = x27/x28;

x30 = x6/3;

x31 = 2*x7;

x32 = x24 - x26 + x29 + x30 + x31;

Q(j) = x32;

fprintf(fid1, '%f\t %f \t %f \r\n', Gr(i), M(j), Q(j));

Gr(i+1)=Gr(i)+10;

M(j+1)=M(j)+0.01;

end

fprintf(fid1,'-----------------------------------------------\r\n');

plot(a,Q,'r--');

%plot(x,z3,'r--')

%%plot(x,y1,'g',x,y2,'b--o',x,y3,'c*')

xlabel('M');

ylabel('Q');

title('Rate of Mass Flow');

%legend ('M=20','M=15','M=10','M=5');

hold on

end

fclose(fid1);

hold on
