If you were wondering if it was Ok to have multiple google-site-verification meta tags on your website, the answer is Yes it is.
From Google webmaster central FAQ: Website verification: https://sites.google.com/site/webmasterhelpforum/en/faq-website-verification
Q: How can I give someone else access to my Webmaster Tools account?
A: Each person that needs to access data for your site should create their own Webmaster Tools account and verify that site in their own account. It’s fine for a site to have multiple verification meta tags or HTML files; there should be one meta tag or file per account.
That’s it. You can safely include more than one google-site-verification meta tags on your website.
