I want to calculate ~10 kernel density estimates and overlay them on top of each other with varying transparency such that all X_f are on the same plot.
figure;
ksdensity(X_f(:,1)); hold on
alpha(1)
ksdensity(X_f(:,2)); hold on
alpha(0.8)
ksdensity(X_f(:,3)); hold on
alpha(0.6)
ksdensity(X_f(:,4)); hold on
alpha(0.4)
Is it possible to change the transparency of kernel density estimates in a similar way/or else how can this be done?

ksdensity produces a line object. Line objects have no transparency (alpha) property in Matlab. So no, you can't do what you ask in native Matlab.
That being said, you could always look in the file exchange:
