Gazelle is a nice name for a company, one that emphasizes speed. Currently, Gazelle.com is a used electronics website. The problem is that you own one specific version of Gazelle, which is Gazelle foods. While it can be lucrative to buy common company names, I would try to find a name that is used by a half dozen or so businesses, or at least by a couple well established businesses.
Gazelle foods is used by 2 businesses, only one of which seems viable - and that's in Australia. Do you have the Australian TLD? The US company may not even exist as far as I can see from it's minimal mention on the web. So that leaves one small business in Australia, and your prayer that someone else launches a Gazelle Foods company.
Say your prayer is answered, and someone launches that business - and they are the one out of ten new companies that ever gets off the ground. Why wouldn't they simply register gazellefood.com for $8? Or gazellegourmet.com for the same?
It makes no sense to register the .com of this name, much less all those other extensions, unless you personally want to start a Gazelle Food Company. Even then, you would be wasting your money on the .eu, .mobi and other extensions. And I think it's a marginal name for a food company, as it does suggest gazelle meat.
If you want to flip, there are 100s of better names that drop daily. If you want to buy names of existing businesses, find a name that's common enough to have multiple businesses named after it - and make sure that at least one or two of those are actually going businesses rather than just some dream that some guy registered with some business registry.
