The answer to the headline question is a simple yes. You can vote for, against or abstain for any motion which is presented.
An individual Cllrs vote is a responsibility and a precious gift. It should neither be forced, compelled or induced other than by the considered free will of the Cllr.
If there is a majority of votes for, the motion is passed, if not, it fails.
A side question….
Is it the meeting or the council that must have a chair?
A chairs role is no more or less than any other Cllr except in that they must preside over the meeting at hand.
You could just elect a chair for any given meeting.
