Hello,

Question is Confusing!!!

You have running instances or You want to have 5 node RAC???

RAC is Option that allows multiple concurrent instances to share a single physical database.Each instance runs on seperate server in cluster.When you want additional resources are required additional nodes and instances can be added with no downtime.

[original link is broken] this will help you.

You can Migrate the primary database to RAC.

The process of adding nodes to form a RAC database involves first cloning Oracle Clusterware and RAC software to new nodes and then adding new RAC instances. Basically, the steps include the following tasks:

Connect new nodes to the cluster

Extend clusterware and Oracle software to new nodes

Prepare storage for RAC on new nodes

Add nodes at the Oracle RAC database layer

Add database instances to new nodes
