You don't mention when you what the validation to run, or the type of project you are using. A bit more context would help the community answer more directly. 

If you want the UI to validate custom fields when editing them - I don't think there is any existing Jira feature for that. But you could use Jira automation to do it - feedback would be delayed, and could be via an email/notification or issue comment. 

Assuming you want to validate this in a workflow transition (changing the work item status), this is common to ensure data is complete or valid before the issue can be closed or resolved.

I know of two ways to do this - and they work differently.

1. Use a workflow validator - we use ScriptRunner to do this kind of thing. This has the benefit of preventing the issue status change. I think you'd need an app to do the kind of validation you describe.
2. Use Jira Automation - this also works well for more complex logic, but the downsides are:
   • These are asynchronous - they run after a few seconds. i.e., they cannot give users immediate feedback and they cannot prevent a workflow transition.
   • The issue would transition, to the next state, and then need to be transitioned back by the automation if the data is not valid.
