If n-1=2 nodes go down you will start loosing data. So that means if both the nodes go down you will loose data.

replication factor N, we will tolerate up to N-1 server failures without losing any records
Replication Factor means number of nodes/brokers which could go down before we start losing data.
So if you have a replication factor of 6 for a 11 node cluster, then you will be fault tolerant till 5 nodes go down. After that point you are going to loose data for a particular partition.
