I have 4 excel files that all start with THA and there are 4 types(THA1, THA2, THA3 & THA4) the full file name for all 4 are like this: THA1_343fdf and I want to extract all four file names by filtering it with THA if possible. I can extract the data easily but struggling with extracting all 4 file names.

tData=readtable(fullfile(d(i).folder,"d(i)name"))
It's doing exactly what you told it to do -- it's looking for the literal string "d(i)name" as the file name, not the next file in the dir() struct d() array that you returned.
Look at the documentation for dir and the examples there and look at what the call returns in the variable d struct at the command line to understand what you're doing here.
The code is, as I wrote initially,
tData=readtable(fullfile(d(i).folder,d(i)name));
Remove the quotes; they don't belong...

never mind, this is how it should look, correct?
d=dir(fullfile('C:\Users\R101951\Desktop\RB\New folder','THA*.*'));
for i=1:numel(d)
tData=readtable(fullfile(d(i).folder,d(i).name));
end

more something like that?
for type=1:4
basepath='C:\Users\R101951\Desktop\RB\New folder\';
currFile=dir([basepath 'THA' num2str(type) '*.xls']).name;
data=readtable(currFile,.....);
end
the ' * ' is a wildcard for the '_343fdf' part which I assumed is not the same for every file you are interested in
