Tooltip how to rename more than one equation

Question

Manual shows renaming of one equation in Tooltip. If you have multiple equations in a single plot, how can I rename each equation?? Having Tooltip display lengthy equations if of little value, therefore a better nomenclature is needed, but it appears Mathematica will only allow one renaming???

This question is a bit too general and I have to admit that I do not understant the issue at all. Usually, it is helpful to give a short minimal example that highlights your problem. — Henrik Schumacher, Mar 06 '20 at 18:53

funcs = Hypergeometric2F1[2., 3., 4., #] & /@
   {x, x^2, Sin[x], Cos[x]};

Plot[
 Evaluate[Tooltip[#, #[[-1]]] & /@ funcs],
 {x, -2, 2},
 PlotLegends -> Placed[(Last /@ funcs), {.85, .35}],
 PlotRange -> {0, 20},
 PlotLabel -> Hypergeometric2F1[2., 3., 4., f[x]]]

Or

labels = {x, x^2, Sin[x], Cos[x]};

Plot[Evaluate[(Tooltip @@ #) & /@ Transpose[{funcs, labels}]],
 {x, -2, 2},
 PlotLegends -> Placed[labels, {.85, .35}],
 PlotRange -> {0, 20},
 PlotLabel -> Hypergeometric2F1[2., 3., 4., f[x]]]

Thanks very much, Bob, I was hoping for something simpler. When I see @, @@, /@, &/@ my eyes kind of glass over. I knew once, but lack of use I have forgotten again -- any good resources to explain what these symbols mean??? – ray Mar 11 '20 at 22:03
@ray - Highlight the symbol of interest and press F1 on your keyboard for help. See also What the @#%^&*?! do all those funny signs mean? – Bob Hanlon Mar 11 '20 at 22:10
