You can use Get/@ FileNames["save*"].

There are several issues. First of all Context[] is the same here and can be replaced with $Context to make the example clearer. Now:
DumpSave is HoldRest so in case of symbol = 2 it can save that definition instead of seeing 2.
DumpSave["file", symbol] will save defnitions of symbol. So will DumpSave["file", $Context]. It will save information that $...

The function that does the actual calculation:
fcalc[n_] := n^2
make file names:
SetDirectory[NotebookDirectory[]];
makeFileName[n_] := "cachefile_" <> ToString[n] <> ".wl"
The function that you call from the rest of the code:
Clear[f];
f[n_] := f[n] = Module[{name, F},
(* is there a cached version? *)
name = makeFileName[n];
If[...

Get /@ StringTemplate["save``"] /@ Range[1, 5]

Notice that DumpSave has attribute HoldRest which prevents evaluation of all but its first argument.
The documentation of Evaluate states:
You can use Evaluate to override HoldFirst etc. attributes of built-in
functions.
Evaluate only overrides HoldFirst etc. attributes when it appears directly as the head of the function argument that would ...

I suspect that
Files written by DumpSave cannot be exchanged between operating systems that differ in $SystemWordLength.
which is quoted from the documentation article on DumpSace, is relevant to your problem. Evaluated $SystemWordLength on both computers. Are they different?

guidance to your comment:
define some user functions sin,cos
data
= Table[{x, Sin[x], Cos[x]}, {x, Subdivide[0, 2 Pi, 50]}];
sin = Interpolation[data[[All, {1, 2}]]];
cos = Interpolation[data[[All, {1, 3}]]];
save the functions
DumpSave["sincos.mx", {sin, cos}]
Clear[sin,cos] (* new session*)
load function
Get["sincos.mx"]
now the ...

The step data is stored in the interpolating function:
sol = NDSolveValue[{D[u[t, x], t] ==
0.1 D[u[t, x], x, x] + u[t, x] D[u[t, x], x],
u[0, x] == Cos[2 Pi x], u[t, 0] == u[t, 1]},
u, {t, 0, 1}, {x, 0, 1}, Method -> "StiffnessSwitching"];
sol["Coordinates"][[1]]
