Personal pronouns (I, me, mine, yours, etcetera) in Greek work the same as in English, and apart perhaps from there being slightly more forms in Greek, there is no real mystery involved. The third person personal pronouns are forms of the familiar word αυτος (autos). The first person personal pronoun nominative single is the equally familiar word εγω (ego).
As in English, there are no genders to the first and second person personal pronouns. Also note that the obvious declinations of verbal forms often make personal pronouns superfluous.
First person pronouns
The first person singular may come prefixed with an ε (e) for added stress or emphasis (Matthew 5:11: they persecute you because of Me.) In post-Biblical times, the second person personal pronouns became augmented with accents to achieve the same. The nominative, dative and accusative forms of the first person personal pronoun may be welded together with the particle of conjunction και (kai) to make a so-called crasis form that means "I too", or "to me too" (Matthew 2:8).

First person possessive pronouns
The genitive form of the personal pronoun can be used to express possession. But for added emphasis an author may turn to the possessive pronouns. These pronouns behave like adjectives and assume therefore double number, one for the subject and one for the object:
|singular||my (thing)||my (things)|
|plural||our (thing)||our (things)|
The nominative masculine single form of the first person single possessive pronoun (my thing) is εμος (emos, from the emphatic εμου, emou, meaning "of me"), but it comes in many varieties of cases and numbers. It can usually be translated with "mine" or "my own" (Matthew 18:20, Romans 3:7).
The nominative masculine single form of the first person plural possessive pronoun (our thing) is ημετερος (hemeteros, from ημεις, emeis, meaning "we"). It can usually be translated with "our" or "our own" (Acts 2:11, Romans 15:4).
Second person pronouns
Slightly less elaborate are the personal pronouns of the second person. When the New Testament was written, these second person pronouns couldn't be emphasized, and emphases were later added (along with all the other accents). Modern English is rather unusual in that it makes no distinction between the singular and plural forms of the second person personal pronouns, but in the olden days people would speak of "thou/thee/thy" for the single forms and "ye/you" for the plural.
|Koine Greek second person personal pronouns|
|case and number||forms||English|
|genitive single||σου||of you, your|
|dative single||σοι||to you|
|genitive plural||υμων||of you, your|
|dative plural||υμιν||to you|
Second person possessive pronouns
The nominative masculine single form of the second person single possessive pronoun (thy thing) is σος (sos, from συ, su, meaning "you" singular). It can usually be translated with "your(s)" or "your own" (Matthew 7:3, John 17:6).
The nominative masculine single form of the second person plural possessive pronoun (your thing) is υμετερος (humeteros, from υμεις, humeis, meaning "you" plural). It can usually be translated with "your" or "your own" (Luke 6:20, 1 Corinthians 15:31).
