Yes, you can. :-)
You just need to register your domain, write a lot of valuable content, promote them in the web and get links, be helpful with your users and work everyday on your website. That's all.
The value of the keywords in the domain will not affect the SERPs while all of you have almost the same keywords there in.
There's no .com domain?
There's no issues regarding trademarks?
