If you want to use a loop, how are the wanted files recognized? We cannot guess, which 20 files you want. But a meaningful example code must contain a method to determine the files. So please reveal the details.

With a loop:
Folder = 'C:\Your\Path'; % Adjust the path to your needs
List = dir(fullfile(Folder, '*.mat'));
C = cell(size(List));
for k = 1:numel(List)
Data = load(fullfile(Folder, List(k).name));
M = Data.??? % Unfortunately you do not reveal what in the MAT files is.
% Perhaps:
% M = Data.Value;
C{k} = imresize(M, [512, 512]); % See KSSV's answer
end
Result = cat(3, C{:});
save('Output.mat', 'Result');

A = rand(512,1024,128) ;
B = rand(668,512,64) ;
C = rand(512,512,49) ;
Ai = imresize(A,[512,512]) ;
Bi = imresize(B,[512,512]) ;
Ci = imresize(C,[512,512]) ;
iwant = cat(3,Ai,Bi,Ci) ;
