Variables for multiple data files plotting using same Mathematica notebook

Question

I am not an expert in mathematica,

I have this following code. As you see I import a text file under the name "MyPoint1", plot with "pAll" then I do some more calculation with more variables and plots.

MyPoints = Import["/Users/Erf/Documents/points_results/test1_10.txt", "Data"];

MyPoints1 = Table[{MyPoints[[i]][[1]], MyPoints[[i]][[2]]}, {i, 1, Length[MyPoints]}];

pAll = ListPlot[MyPoints1, AspectRatio -> Automatic, 
 PlotStyle -> PointSize[0.0051], PlotRange -> {{0, 1200}, {0, 700}}]

nebs1[i_] :=( 
list1[i] = {};
 Do[distX = Abs[MyPoints1[[i]][[1]] - MyPoints1[[j]]][[1]];
  distY = Abs[MyPoints1[[i]][[2]] - MyPoints1[[j]][[2]]];
  If[Sqrt[distX^2 + distY^2] < 12,AppendTo[listy[i], j],Continue],{j, 1, i - 1)];
 Do[distX = Abs[MyPoints1[[i]][[1]] - MyPoints1[[j]]][[1]];
  distY = Abs[MyPoints1[[i]][[2]] - MyPoints1[[j]][[2]]];
  If[Sqrt[distX^2 + distY^2] < 12,AppendTo[listy[i], j], Continue],{j, i + 1, Length[MyPoints]}];

pP[i_] := 
ListPlot[{blob2[[i]]}, AspectRatio -> Automatic, 
 PlotStyle -> Directive[PointSize[0.1], Black], 
 PlotRange -> {{1, 100}, {1, 100}}]

pN[i_] := 
ListPlot[Table[MyPoints1[[list1[i][[j]]]], {j, 1, Length[list1[i]]}], 
 AspectRatio -> Automatic, 
 PlotStyle -> Directive[PointSize[0.1], Red], 
 PlotRange -> {{1, 100}, {1, 100}}]
pN2[i_] := 
ListPlot[Table[MyPoints1[[list1[i][[j]]]], {j, 1, Length[list1[i]]}], 
 AspectRatio -> Automatic, 
 PlotStyle -> Directive[PointSize[0.1], Red], 
 PlotRange -> {{MyPoints1[[i]][[1]] - 20, 
    MyPoints1[[i]][[1]] + 20}, {MyPoints1[[i]][[2]] - 20, 
    MyPoints1[[i]][[2]] + 20}}]

Table[Show[pN2[ii], pP[ii]], {ii, 371, 373}]
.
.
.
.

If i have 10 or 20 data files and want to plot them all in the same mathematica notebook, every time I have to rename all the variables (i.e. Mypoints, pAll, list1, etc.) So I want to know if there is an easy way to define variables such that I don't have to rename them?

I can restart the kernel and all the variable are gonna be new for a new text file, but then my plots are not gonna be saved and I cannot change them. The other way I tried is to Find/Replace the variable, but that again is tedious. Maybe there is a way to loop everything, but again I am not an expert.

Any help and guidance is appreciated. Thank you
