In your example you generate a legend for every plot at the same place.
A legend can't be longer or higher than the plot itself.

You can specify the place of every key entry separately in the plot
command. Than you can place the key entry where ever you want.

I don't know if this works with gnuplot 4.6, I tested it with gnuplot 5.2



set xrange [-pi:pi]
set key at screen 1,1
set key maxcols 1
set multiplot layout 2,3 columnsfirst scale 1.0, 1.0
plot 10*sin(1*x) w l t 'sin' at 0.9,0.9,\
     10*sin(2*x) w l t 'sin' at 0.9,0.86,\
     10*sin(1*x) w l t 'sin' at 0.9,0.82,\
     10*sin(2*x) w l t 'sin' at 0.9,0.78,\
     10*sin(2*x) w l t 'sin' at 0.9,0.74,\
     10*cos(1*x) w l t 'cos' at 0.9,0.70,\
     10*cos(2*x) w l t 'cos' at 0.9,0.66,\
     10*cos(1*x) w l t 'cos' at 0.9,0.62,\
