Unless the files are all the same sampling frequency and the same number of samples and the same number of channels, then I recommend

overall_dataset = {Normal; Asthma; Pneumonia; BRON; COPD; HeartFailure};

along with storing the sampling frequency for each in a numeric vector unless you know that they are all the same.

but theey have different number of samples :(

Then use {} like I show. Afterwards you would be able to do things such as

size(overall_dataset{2}, 1)

to find the number of samples for the Asthma dataset.

Depending what you are doing, you might want to instead create a table,

dataset_name = {'Normal'; 'Asthma'; 'Pneumonia'; 'BRON'; 'COPD', 'HeartFailure'};
Data = {Normal; Asthma; Pneumonia; BRON; COPD; HeartFailure};
Frequency = [18000; 12000; 18000; 18000; 36000; 12000];

T = table(Data, Frequency, 'RowNames', dataset_name);

Afterwards you would be able to do things like

T.Frequency('Asthma')
