Subject pronouns: yo, tú, vos, él...
Yo, tú/vos, él/ella/usted, nosotros/as, vosotros/as, ellos/ellas/ustedes. Usted takes third-person verb forms despite meaning 'you'.

Explicación
The subject pronouns are yo, tú (and vos in voseo regions), él, ella, usted, nosotros/nosotras, vosotros/vosotras, ellos, ellas, ustedes. They name who performs the action, though Spanish usually omits them because the verb ending already shows the person (see the rule on dropping subject pronouns).
Two points trip up learners. First, usted and ustedes mean 'you' but take third-person verb forms: usted habla, ustedes hablan — a politeness leftover from 'your grace'. Second, the feminine plurals nosotras, vosotras, ellas are used for all-female groups; a mixed group defaults to the masculine.
Regionally: vos replaces or coexists with tú across much of Latin America (Argentina, Uruguay, Paraguay, Bolivia, Central America), with its own verb forms; and vosotros (informal 'you all') is used only in Spain — Latin America uses ustedes for every plural 'you', formal or not.
