How many times the One time schedule processes can be run

We have a requirement where we have to do some page composure personalization in requisition for which we need to create a requisition in SIT/UAT or Prod environment. Data load will be done in phases which may take lot of time. So to complete the personalization can we run the following processes (mentioned as one time in implementation guide) before data load and then can those processes be run again after data load.

Process names:

1. Load and Index Candidates
2. Load and Index Job Requisitions
3. Load and Index TCA Geographies
4. Load Workers into the Candidate Table
