The English language doesn't use 'passive' pronouns.
If you meant 'possessive' pronouns, they are: mine, yours, his, hers, its, ours, theirs.
The possessive pronoun that would take the place of a noun for something belonging to ancient Egyptians is theirs. Example:
The ancient Egyptians designed architechural marvels, for example, the classic style pyramid is theirs.
The active subject is the noun or pronoun that performs the action in a sentence. The passive subject is the noun or pronoun that receives the action in a sentence, rather than performing it.
I assume you are thinking of a sentence like "I massaged myself." with the reflexive pronoun "myself". In a sentence like this the subject and object are the same person, so by putting it into the passive, you make the object the subject. Except that the object is already the subject, so the passive form comes out "I was massaged by myself." It is almost the same. Same thing with third person reflexives. "She poisoned herself" is "She was poisoned by herself" in the passive.
No, we is a pronoun, the first person plural personal pronoun. There is a possessive adjective, our, and a possessive pronoun, ours. Our is the only modifier.
