The elements of both lists are given as
A={9,5,9,3}, B={9,9,5,5}
In this case, how can I list the list {9,5,9} of the common elements of the two lists?
(The order does not matter.)

in the output:
In[1]:= Flatten[KeyValueMap[ConstantArray, Merge[KeyIntersection[Counts /@ {{9, 5, 9, 3}, {9, 9, 5, 5}}], Min]], 1]
Out[1]:= {9, 9, 5}
If you didn't need the duplicate 9
you could just use the Intersection
function.
