Usually the "easiest" language to learn is the one you're most excited about though. If you do not practice often you will not improve, and if you are not excited about your new language you probably will not practice enough. In your case though, Spanish should be much easier for you than the others. Spanish and Portuguese have a lot in common.

Hello I am a farsi native speaker. I'm studying spanish by myself and i think it is very easy. It is easier than english! for example When you study english you may can't pronounce most of words correctly because there are differences between spelling and pronounciation but in spanish there are only some basic rules which help you to read any words correctly
