My book says that the nostrum can also be nostri, and vestrum can be vestri, and that the "he" pronoun-thing's nominative plural is ei.
Along this same vein though:
Reflexive pronouns:
Genitive: sui
Dative: sibi
Accusative: se
Ablative: se
(same forms in singular and plural)
This is for saying himself/herself/itself, also used any time you want to say "he" or "she" or "it' but in reference to the subject of the current sentence. There's no nominative, since the subject woudn't be repeated in the nominative. You can use it like:
Quintus washed
himself.
Quintus
se lavit.
Or with an accusative subject in something indirect:
Quintus said that
he
Quintus dixit
se....
Etc.
Relative Pronoun (who, which)
Singular (masculine, feminine, neuter)
Nominative: qui, quae, quod
Genitive: cuius, cuius, cuius
Dative: cui, cui, cui
Accusative: quem, quam, quod
Ablative: quo, qua, quo
Plural (masculine, feminine, neuter)
Nominative: qui, quae, quae
Genitive: quorum, quarum, quorum
Dative: quibus, quibus, quibus
Accusative: quos, quas, quae
Ablative: quibus, quibus, quibus
Demonstrative Pronouns
That's what the book calls them anyway.... basically, the hic, haec, hoc pronoun is used for saying "
this thing" or "
that thing", and the ille, illa, illud pronoun is a stronger version of the he/she/it that Lucifer posted. If the he/she/it you're using was the subject of the previous sentence, you use ille/illa/illud. If it's something completely different, you use is/ea/id.
Quintus. went to a lecture. Then he.... (he = ille)
Quintus saw Marcus. Then he (= ille) called to him (Marcus = eum)
Hope that made sense. Anyway, the forms.

There are a few more pronouns and the like, but they're not used nearly as much, so I'll spare you all.
