Russian personal pronouns

In Russian language pronouns are words that are used to replace other nouns or pronouns to simplify a sentence and to avoid repetitions. Personal pronouns refer to a specific person or a thing you are talking about.

я (I), ты (you - singular),он (he), онá (she), онó (it - neutral) мы (we), вы (you - plural), они (they).

единственное число			множественное число
я			мы
ты			вы
он	она	оно	они

In Russian ты is generally used among people who know each other very well. Otherwise, it is more appropriate to use formal вы.
