Octave tries to duplicate Matlab's implementation of plotyy and legend.
x1 = 0:5:10;
x2 = 0:10;
y1 = rand (size (x1));
y2 = rand (size (x2));
[ax, h1, h2] = plotyy (x1, y1, x2, y2, @plot, @plot);
y1Label = "y1";
y2Label = "y2";
The command below should produce the desired legend (please check, the
implementation may have changed since 3.4.0).
legend ([h1, h2], {y1Label, y2Label}, "location", "south")
The commands below should also work, but currently reverse the legend entries.
legend ({y1Label, y2Label}, "location", "south")
legend (y1Label, y2Label, "location", "south");
I've entered a bug report in the tracker.

Regarding "Fontsize", the legend function doesn't accept property names/values
as input.
To change the fontname, the legend command returns the handle to the legend.
You can change its fontname property directly.
h = legend ([h1, h2], {y1Label, y2Label}, "location", "south")
set (h, "fontname",'Helvetica")
