There are probably a lot more than just these, but I can think of at least one example for each off the top of my head.
He is generous. We see that because he is willing to do legal work for Walter Cunningham even though Cunningham can't really pay. He will take his "pay" whenever and in whatever form they can manage.
He is open-minded. He gives Calpurnia much more respect than most people give their black servants. In fact, he does not really treat her like a servant.
He is brave to defend Tom Robinson at all, and he is brave in particular when he faces the mob that comes to lynch Tom. He could have been killled...
