If you have legit versions of Maya and Unity, and if you own the content and not the school, and you've done this work from your home machine, then yes, it should be okay to submit to AssetStore. If you want to sell content on the AssetStore, then you'll need some kind of website so people can see who you are and where you are based.
Also, your Unity account name is a bit strange, and makes you look like someone who's hiding.
