Just read they terms and conditions and if your blog comply with it you should be approved. I can't see any reason why you should not be able to do it. Anyway Good luck
You can have a try. Google would like good blog which contains more original and attractive contents.
You might want to invest $10 to get a domain name forwarded the blog (if it is not approved the first time)
yes, you can. As long as your blog is quality blog and doesnt against any adsense TOS, you will get approved
You can get adsense account if you have quality content in your blogspot. Otherwise it won't get accepted. If you fail to get the account. PM me. I will set it up for you one.
If you have a personal domain and host and more than 5 posts .the chances of adsense approval is high.
