Do I need to know the non-glossary vocabularies?

Do I need to know only the vocabs listed as glossaries or any terminology in the textbook is examinable?

Any terminology is examinable.

Are the 1500 ish glossary in level 1 just for level 1 or for the entire CFA curriculum?

Each level has its own glossary; there’s some overlap, but they’re different.

so what is the combined number of unique glossary in the entire CFA curriculum?

I don’t know.

But I think that you’re focusing on the wrong thing.

Concentrate on passing Level I; forget about Levels II and III until you’ve done so.

Sorry, mea culpa.
