Just read each file in turn and save the first N lines...
NLines=10; % how many wanted to save...make variable so can change at will...
d=dir('Appropriate*WildCardPattern*.csv');
for i=1:numel(d)
data=csvread(d(i).name);
data=data(1:NLines,:);
...
% do whatever with this file's data here...
end

You said were .csv files...those are Excel files--use an appropriate way to read Excell file.
