Are you using bitcask, or LevelDB? What version of Riak are you using? Bitcask will lazily merge files in the background in order to reclaim space. This is pretty aggressive, and it should show up pretty quickly. On the other hand, LevelDB deletes files at compaction time. Compactions aren't quite as aggressive as Bitcask, although in 2.X, some of this was made better.
As to your other question, if you add a 6th node, ideally, it should handoff vnodes and receive an equal share of the load as the remaining 5 nodes in your cluster, but disk usage may not look the same, as only live data, and tombstones are moved over. The recommendation in this scenario is to add nodes to your cluster. If handoffs don't occur quickly enough, it may be wise to bump the handoff limits.
