Yes, you should put each on a separate page, so each has its own link and address (see our Footer).
Article 7 of General Data Protection Regulation (GDPR) provides that when the processing of data is based on the user giving consent, you must be able to show that the user agreed to the processing of the data.
This means that if you place all your policies on one page, you will not be able to show that the user agreed to the processing of their data because they agreed to all-of-the-things. So the user could say “Yes, I agreed to the Terms of Service, but not to the Privacy Policy.”
If GDPR doesn’t apply to you, this is still good practice. For example, the California Online Privacy Protection Act of 2003, which states that you must “conspicuously post” the Privacy Policy. This means a separate link.
