The origins of specific Lithuanian surnames are hard to find because of the lack of sources. However, most of them are composed of a root and a suffix so that the names you've submitted can be divided pretty much as follows: Abr+aitis, Adak+onis, Adaške+vičius, Aglin+skas, and Andziu+lis (there's no Aldziulis) which looks like it could be Andrew.
