6. Data stored on Kafka Topics
7. HBase data

Answer: 2,3,4,5

Exp: Replication Manager enables you to replicate data across data centers for disaster recovery scenarios. Replications can include data stored in HDFS, data stored in Hive tables, Hive metastore data, and Impala metadata (catalog server metadata) associated with Impala tables registered in the Hive metastore. 

You can also use the HBase shell to replicate HBase data. (Cloudera Manager does not manage HBase replications.)
