I have a list with 9 different vectors inside. And I want plot them (dot-line) in one figure with different colors by their names. How to do that in R language?

The individual numbers that make up a vector are called elements or components of the vector. and vector addition. Two vectors of the same size (i.e. number of elements) can be added: this adds the corresponding elements to create a new vector of the same size. You can't add two vectors of different sizes.
To draw a plot from two vectors in R, where one vector represents data points along X axis, and the other vector represents data points along Y axis, call plot() function and pass the two vectors as arguments to the plot() function.
Using a made up example:
# example data:
dat <- list(a=1:5,b=2:7,c=3:10)
# get plotting:
plot(unlist(dat),type="n",xlim=c(1,max(sapply(dat,length))))
mapply(lines,dat,col=seq_along(dat),lty=2)
legend("topleft",names(dat),lty=2,col=seq_along(dat))
