the different forms of "our"
I have trouble identifying the different forms of "OUR" in masc., fem. & neut. (nom., acc., etc.), etc. And is there a good website I can use for that?
It just takes practice.
Note. If you can conjugate first and second declension nouns, you can conjugate (many) adjectives and possessive pronouns (termination adjectives take 3rd declension endings). The endings are pretty much the same.

Don't forget that all adjectives (of the same type: here, the "us, a, um" type, or 1st/2nd decl. adjectives) use the same endings; so it's not as if you're learning special endings for each discrete adjective, or something crazy!
The adjective 'follows its noun' in 3 particulars: it must be in the same CASE (nom/gen/dat/acc/abl/voc), in the same NUMBER (meaning, singular vs. plural), and in the same GENDER (masc/fem/neuter).
So perhaps I may speak of pater noster , our father. That's the form when he's nominative (singular, masculine). Pater noster est in urbe, Our father is in the city.
But suppose "our father" is also the object of the verb: Patrem nostrum visitamus. (We are visiting our father.) . Notice how both the noun and the adj. changed, from nomin. to accusative. (Notice that they don't use identical endings, because they belong to different declensions: pater is a 3rd decl. noun; since it's masculine, it uses a 2nd decl. noun, for "our.")
Suppose it's "the letter of our father " that we're talking about? Nuntius ad me epistulam patris nostri portat (The messenger brings to me the letter of our father). The phrase is now genitive, showing possession.
Necesse est patri nostro ad urbem ire. (It's necessary for our father to go to the city.) . dative
Iter facimus cum patre nostro. (We're traveling with our father.) . The preposition cum requires ablative.
