This is a very broad request. So, let me simply go over one point and one way of tackling such a large issue.
From a methodological point of view, it might be best to examine this question from the perspective of a single theme. For example, study their view of certain topics. For example, study their view of the theology of worship, or the afterlife, and the like. This approach will allow you to compare and contrast these religions.
If I consider one topic, it would be their belief in the divine. Confucianism does not necessarily espouse a strong view of the divine, as it is more of a philosophical system of thought. This is in stark difference with Christianity, Judaism, and Islam. These latter three religions are strictly monotheistic. When it comes to Buddhism, again there is no strong belief in the divine. It is more a religion that emphasizes causal connections. When it comes to Hinduism, again we come to something even more different, because Hinduism believes in many gods. It is polytheistic.
