is this word noun or verb?

It's not a verb or noun. What do you think "present" is?.

if you have an answer please tell. if i know i wouldn't ask

lost manif you have an answer please tell. if i know i wouldn't ask

But you can still think about it and you might learn something in the process.
Is it a pronoun, adjective, adverb, preposition or conjunction?

The word present is an interesting one because the verb form and the adjective form are pronounced with different stress.

Verb:
The mayor presented the city budget to the council. (Bold face is stressed)
The winner of the national science prize was presented to the Queen who personally gave her the award.

Adjective:
Teacher (calling role)
T: J

Thanks to all of you.

I think the adjective "present" is part of a reduced relative clause. ... has to secure a two-thirds vote of members who are present in both houses of Congress.

You are exactly right.
