All of them.

There is no posted technical limitation. However, more than 2000 becomes difficult to manage and can incur performance penalties.

@steve.behnke’s answer got me thinking. As he asserts, there is no published limit for company-managed projects. However, for team-managed projects there is a published limit:

You can create up to 50 custom fields in your project.

That limit is the same for UI and API.
