You can do a "dummyplot" only for the key. This works with older 
versions than 5.2

reset
unset key
set xrange [-pi:pi]
set multiplot
set size 0.4,0.5
set origin 0.0,0.0
plot for [i=1:5] 10*sin(i*x) w l t 'sin',\
      for [i=1:5] 10*cos(i*x) w l t 'cos',\
      for [i=1:5]     i*x     w l t 'line',\
      for [i=1:5]    -i*x     w l t 'line'

set size 0.4,0.5
set origin 0.0,0.5
replot

set size 0.4,0.5
set origin 0.4,0.0
replot

set size 0.4,0.5
set origin 0.4,0.5
replot

#---dummyplot--------
set key left
set size 0.2,1.0
set origin 0.8,0.0
unset grid
unset tics
unset border
set xrange [0:1]
set yrange [0:1]
plot for [i=1:5] (10*sin(i*x))-10 w l t 'sin',\
      for [i=1:5] (10*cos(i*x))-10 w l t 'cos',\
      for [i=1:5]     (i*x)-10     w l t 'line',\
      for [i=1:5]    (-i*x)-10     w l t 'line'

unset multiplot
