Yes you definitely can, just because someone lives in a different state doesn't mean that they are immune to American law re: restraining orders. If you think you need one (because you feel threatened or intimidated or believe you are being harrassed), go ahead and contact a lawyer to start dealing with the process. You'll normally get one granted for up to a month without the named person being present - it's just you that attends the initial hearing to grant an "ex parte" (basically a temporary) restraining order. Learn more about what happens, and the difference, here: Fighting A Restraining Order: Temporary vs. Permanent . Good luck and I hope that helps!
Yes it does thank you.
