The folder with wrong permissions is different in the error message. OK, let me highlight this for you:
Joomla\CMS\Filesystem\Folder::create: Could not create folder.Path: /var/www/html/irishdancenm.org/public_html/media/com_akeeba/fonts
Cannot create destination folder
This is the folder you need to delete before trying to install the update.
As you may have figured, these are all server issues. Most likely causes are ownership, permissions or filesystem corruption. I'm afraid that since these are unrelated to our software and I don't manage any CentOS servers of my own (I use Ubuntu Server everywhere, before that it was Mandrake / Mandriva for me) I can't help much :(
