No.

By using the title-option within the plot-command you may 
place every kind ot text your chosen terminal is able to 
work with into the key entry of that particular plot. 
   plot 'junkresidl' index n:n u 3:4 title "%n" w l lt (n+1)
Many terminals support various commands for producing e.g. 
indices or superscripts or italic text. 

See help title and help terminal for more details. 

BTW: You loop will produce 10 new plots, since every 
plot-command leads to a new output. Maybe the facilities of 
replot may help you with this, see help replot.
