Since Spanish verbs are much more inflected than English ones, learning those inflections requires you to memorise them, I mean, you can't say I are, nor can you say yo eres, and this is the easy part, you better start studying grammar and you'll get a better idea on how it works.
i'm only a begginer in spanish but i think that Soy is used when you're talkin about yourself : (Yo) Soy= I am, Es is used with El, Ella and Usted: (El/Ella/usted) es = he/she/you(formal) is, and Son is used with Ellos, ellas ans ustedes: (Ellos/Ellas/ustedes) Son= They/You(plural) are.
As well as the lessons here you may find this one useful - Getting started with Spanish

exp: Soy estudiante= Iam a student (Ella) es estudiante= she is a student (Ellos) Son estudiantes= they are students
there is also "eres" which is used with tú (you informal): (Tú) eres estudiante = you are a student.
