During project execution, the cost management plan would be used to:

Ensuring fair compensation for resources is typically covered by human resource management plans or organizational policies, not the cost management plan itself.

Scheduling resources is part of the resource management plan and schedule management plan, not the cost management plan.

Identifying previously unidentified costs is a continuous process that might inform updates to cost estimates, but the cost management plan primarily focuses on controlling known or estimated costs rather than discovering new ones.

During project execution, the cost management plan provides the guidelines and procedures for monitoring actual project costs against the baseline and determining if any cost variances exceed acceptable thresholds, triggering corrective actions. This is a core function of cost control outlined in the plan.
