Try this:

set output 'plot.eps'

set key below
plot sin(x) title "{/Arial=8 LongFunctionKeyName}", \
 sin(2*x) title "{/Arial=8 LongFunctionKeyName}", \
 sin(3*x) title "{/Arial=8 LongFunctionKeyName}", \
 sin(4*x) title "{/Arial=8 LongFunctionKeyName}", \
 sin(5*x) title "{/Arial=8 LongFunctionKeyName}", \
 sin(6*x) title "{/Arial=8 LongFunctionKeyName}", \
 sin(7*x) title "{/Arial=8 LongFunctionKeyName}", \
 sin(8*x) title "{/Arial=8 LongFunctionKeyName}", \
 sin(9*x) title "{/Arial=8 LongFunctionKeyName}", \
 sin(10*x) title "{/Arial=8 LongFunctionKeyName}", \
 sin(11*x) title "{/Arial=8 LongFunctionKeyName}", \
 sin(12*x) title "{/Arial=8 LongFunctionKeyName}", \

Problem

How can I please display gnuplot titles in multiple lines or even in columns. Indeed I have 8 titles and I juste used this : ``` set key below ``` So each one is displayed in a seperate line. So the figure becomes congested.
