How do we describe this ?

[sympathy]

What do you call this in English ?

1)How can you describe a person who is pressing, bending their finger joints to make a sound ?
And about the sound of this, how will you call it ? It is a "crack" or a "crackle" or a "click" or a "creak" or a "crunch" ?

2)Let's say our group of students is discussing an issue about education. They have outlined 4 items representing 4 aspects of the issue, but after a while they realize that one aspect belongs to another. They decide to "remove" that item from the discussion. One student say "We must .... this"
How can we say this ? Is "remove" OK to fill in the blank ? Cancel ? Cross out ? I want to know the most commonly used words (spoken language).

Thanks so much

I'd say

1) crack

2) We must cut this off or take it out

Cracking his knuckles
so - It is a "crack"

exclude = remove from consideration
omit = leave out or exclude

Thanks for your help.

I am still wondering about the second question.
Is "exclude" used commonly in spoken English ?

You could say "exclude," but in the context you gave, it would be more common to say "strike this" or "scratch this."
