So, I know that た and ない are attributive such as: 知らない人 - a person that I
don't know of (that they existed? still figuring out 分かる vs 知る)

but can you use any form of a verb to be attributive? 知れる人 - a person I could
learn of? (potential form)

This would probably never be used, but grammatically is it correct?

Is every form of Japanese verbs attributive?
It's more than attributive usage - it's actually a relative clause, because it
can be a whole sentence (clause) before a verb.

今日買った本 book that (I) bought yesterday

本を買った人man that bought a book

Etc

So it can be past, present, negative, ている form, whatever. However, masu forms
are not used in relative clauses.

> Is every form of Japanese verbs attributive?

No. The imperative form and the hypothetical form never modify a noun. 知れ人 and
知れば人 are always wrong.

Most other "forms" (or strictly speaking,
[助動詞](https://japanese.stackexchange.com/a/63365/5010)) work attributively,
but a few have a special attributive version. In particular, forms that end
with -だ/-です (知りそうだ, 知るようだ) becomes -な when used attributively (知りそうな人,
知るような人).

In classical Japanese, many verbs, adjectives and 助動詞 looked different when
used attributively (e.g., 日落つ = "The sun sets", 落つる日 = "the sun that sets").

Out of modern 6 inflexion bases by definition only attributive (連体形) is used
attributively. Note that な is an attributive form of copula だ, and た is an
attributive form of helper verb つ.
