Is this a fresh install? or are you upgrading an existing Exchnage 2013 CU release? If so which one?

Are you facing any issue with Exchange server with these errors. I don't think error showing above causing any issue on Exchange server. These are general errors and can be ignored.

Typically if you upgrade and you have errors upgrading again before correcting the errors is a bad move. All errors should be resolved before doing a migration.

What aspects of Exchange are not working?

Can you spin up another Ex2013 CU8 server and migrate the mailboxes that you have on the current one?
