It depends little bit on range of your Y values. If it is similar magnitude, then 
simple

matplot(your.df[,1],your.df[,3:6],type="l")

see
?matplot

will do it. But if the range of your Y values is big you have to do some 
"flattening" or to use subsequent plot commands with par(new=T).

See
?plot and ?par
