An example of how to use switch case: adapt for your particular case
busNum=input('Enter the bus number:');
switch busNum
case 1
disp('2 3')
case 2
disp('1 4 6 5')
end

Storing the values in different variables is a bad idea. Better use an array:
bus = {[2 3], ...
[1 4 6 5], ...
[1 4], ...
etc. };
l1 = input('bus connection(choose one number from 1 to 30) = ');
disp(bus{l1});

I suggest you concatenate the numerical input l1 with the string 'bus'. Then display the content with display(). E.g.
X = ['bus' l1];
display(X)

It is not a matter of it working or not. Please look at this previous discussion.
