How to plot multiple lines simultaneously in a single figure?

Question

For example, suppose I want to plot $\sin(x)$ and $x^2 +4 $ as two lines simultaneously in a single figure.

I know Show can do it.

But what if I have 5 lines to plot?

Is there anyway to evade Show? I know in Matlab it is very simple.

You do not need to use Show, just use Plot with the functions to plot in a list.

 Plot[{Sin[x],x^2+4},{x,- Pi, Pi}]

The problem with this method is that, you need an explicit expression of the function. What if you just have some data?

data1={1,2,3,4,5};
data2={1.3,2.4,4.3,5.2};
ListLinePlot[{data1,data2},Mesh->All]

@S. Kohn, so why did you neglect to mention that in your question? – J. M.'s missing motivation Apr 18 '17 at 05:47
