You didn't form the file names properly, so you were trying to read files that don't exist. You're also overwriting the results.

header = 9;
delimiter = '\t';
for i = 1:2
    filname = sprintf('H1, 2_I1sv%05d.txt',i);
    dat(i) =importdata(filname,delimiter,header);
end
dat

dat = 1×2 struct array with fields:
    data
    textdata
    colheaders
