See ?mtext for adding text into the margins.

Given that you have two labels at the same point, you will have to 
stretch out your labels. I took out the X axis label to get enough room.

library(plotrix)
plot(F2.5,
  verticals= TRUE,
  do.p = TRUE,
  lwd=3,
  ylab = "f(x)",
  xlab = "",
  main = "Figur 2.5 Empirische Verteilfunktion",
  xlim = c(1,5.5))
abline(h= (0:5)*0.2)
staxlab(at=x,labels=paste("X[",1:10,"]",sep=""),nlines=3,top.line=2)
