Go to: System Settings > Privacy & Security > Blocked Contacts

Click on Blocked Contacts. You'll first see a line simply showing how many blocked email and phone number entries you have. Presently 101 in my case.

Click on that top line and a list of all entries will appear.

From here, you can choose the entries the same way you would from a list of files and folders in the Finder. Click on any one and then Command+A to select them all. Select one and then Shift+click anywhere above or below to select/deselect a contiguous set. Or Command+click to add/remove single entries in any order.

Click the minus button at the bottom left of the list to remove all selected items

One at a time. Once they are deleted they are also unblocked. You cannot delete the contact but still keep the number blocked. Things simply don't work that way.

To delete a blocked contact on macOS Sequoia, you must first unblock them and then delete their entry from the Contacts app.

Here are the steps to remove a blocked contact:

Click the Apple menu in the top-left corner of your screen and select System Settings.

Click Phone in the sidebar, then select Blocked Contacts.

Select the contact you want to remove and click the minus (-) button at the bottom of the list to unblock them.

Open the Contacts app on your Mac, select the contact, and press the Delete key to remove their entry.
