Catholics believe that all humans have equal dignity – all humans are made in the image and likeness of God and so we believe that God loves all of us equally. So we Catholics should try to treat all humans with that same level of dignity. We must not ridicule, disregard or ignore others just because they have a different faith or have no faith. We should respect them and their beliefs and practices, even if they differ from ours. However we should not confuse our beliefs and practices with theirs:the differences between our beliefs and practices do matter, as do the similarities.
Christianity is closely connected with Judaism and also (to a lesser degree) with Islam as the three religions are linked through the prophet Abraham, they are monotheistic (belief in only one God) and they developed in close proximity with each other. In contrast, there is a greater distance betweenChristianity and other world faiths but there is still much ongoing interfaith engagement which is up lifting and interesting.
As a result, Catholics and non-Christians do not normally worship together as we have differing religious beliefs, language and practices. In inter religious dialogue and at interfaith events, it is more customary for people of different faiths (whilst all present) each to offer prayers in their own faith tradition.
To answer this question in more detail, it’s necessary to distinguish between some different faith groups because of the ways in which those faiths have developed and how they are (or are not)connected with Christianity.Please see the related questions and answers on: What is “ecumenism”? What do “interfaith” and “interreligious” mean? How should Catholics engage with Christians who are not (Roman) Catholics? How should Catholics engage with Jews? How should Catholics engage with Muslims?
