[x,fs] = wavread('file');
t = 0:1/fs:length(x);
plot(t,x);
for stereo files
[y, fs]=wavread(fileName); % Read wave file
sound(y, fs); % Playback
left=y(:,1); % Left channel
right=y(:,2); % Right channel
subplot(2,1,1), plot((1:length(left))/fs, left);
subplot(2,1,2), plot((1:length(right))/fs, right);

Create a matrix in which the left channel is in column 1 and the right channel is in column 2. (If one column would be shorter pad it with 0 to be the same length as the other.) Now play the combined matrix.

Are you trying to make them multiple channels of the same sound? Are you trying to concatenate them together but some of them have different number of channels than the others?
