The active keypair is used to create new signatures, while the passive keypairs can be used to verify previous signatures. This makes it possible to regularly rotate the keys without any downtime or interruption to users. To view the active keys for a realm select the realm in the admin console click on Realm settings then Keys.
This will show the currently active keys for the realm. To view passive or disabled keys select Passive or Disabled. A keypair can have the status Activebut still not be selected as the currently active keypair for the realm. The selected active pair which is used for signatures is selected based on the first key provider sorted by priority that is able to provide an active keypair.
To do so you should start by creating new keys with a higher priority than the existing active keys. Or create new keys with the same priority and making the previous keys passive. Once new keys are available all new tokens and cookies will be signed with the new keys. When a user authenticates to an application the SSO cookie is updated with the new signature. When OpenID Connect tokens are refreshed new tokens are signed with the new keys.
This means that over time all cookies and tokens will use the new keys and after a while the old keys can be removed. How long you wait to delete old keys is a tradeoff between security and making sure all cookies and tokens are updated.
In general it should be acceptable to drop old keys after a few weeks. Users that have not been active in the period between the new keys where added and the old keys removed will have to re-authenticate.
This also applies to offline tokens.
Server Administration Guide
To make sure they are updated the applications need to refresh the tokens before the old keys are removed. As a guideline, it may be a good idea to create new keys every months and delete old keys months after the new keys were created.The first part walks us through booting up the server in standalone mode, setting up the initial admin user, and logging into the Keycloak admin console.

The core concept in Keycloak is a Realm. A realm secures and manages security metadata for a set of users, applications, and registered oauth clients. Users can be created within a specific realm within the Administration console. Roles permission types can be defined at the realm level and you can also set up user role mappings to assign these permissions to specific users.
Generally talking, a client represents a resource which some users can access. Keycloak's built in clients are for keycloak internal use. Realm - A realm manages a set of users, credentials, roles, and groups.
A user belongs to and logs into a realm. Realms are isolated from one another and can only manage and authenticate the users that they control. Clients are entities that can request Keycloak to authenticate a user. Most often, clients are applications and services that want to use Keycloak to secure themselves and provide a single sign-on solution.
Clients can also be entities that just want to request identity information or an access token so that they can securely invoke other services on the network that are secured by Keycloak. For your scenario you can create 5 different clients under one realm. Keycloak provides out of the box support for Single Sign On.

Applications instead are given an identity token or assertion that is cryptographically signed. These tokens can have identity information like username, address, email, and other profile data. They can also hold permission data so that applications can make authorization decisions. These tokens can also be used to make secure invocations on REST-based services.
