As Richardus expalined, there is no person/gender/number agreement in Korean.

Answer

Korean does not have a particular ending for each pronoun. You only have several endings to show the level of politeness. The "dictionary form" of the verb to be is 이다, but depending on the person to whom you are talking to, you can say 입니다, 이세요 etc.
Eg:
Ricardo입니다 / Ricardo에요  (I am Richardus)
누구세요? (Who are you? Polite way)
누구십니까? (Who are you? Quite formal)

Out of context, 이다 (or any of its forms) could mean I/You/He/She/It/We is/am/are.
