Can multiple producers share shame copy of conf? If you can not share same copy of conf, is it ok to share same dr_cb ?

The C API (rd_kafka_new(), rd_kafka_topic_new()) will take ownership of the passed .._conf_t object, so if you want to reuse it for another client or topic you will need to use the .._conf_dup() function to make a copy first.

The C++ factory constructors copies the provided Conf object automatically and does not take ownership of it.

You also mention multithreading: librdkafka is thread-safe and you can use the same producer or consumer client from multiple threads.
