1-What do you mean by they will give me a chance of drawing my PR. ?
Withdraw means to take back or cancel. They may offer you that you can cancel your PR card application for the time being with no ill effect.
2-Does it mean that i have to stay with out PR and other identifications ?
If you have a passport, you are not without identification. You will be without a PR card but you still have your landing papers since the time you landed. You still have your PR status even if you do not have a PR card.
3-For how long ?
Until you meet the residency requirements again, 730 days in Canada that you can prove, and have applied for your PR card renewal and have gotten your new PR card.
4- When can i apply for new PR ?
As said above, when you have 730 days in Canada that you can prove, you can apply for a new PR card.
5-Do you think that i'm allowed to work or study in this case?
Yes, unless they prove that you lied on your application and revoke your PR status and deport you, then you are still PR and can stay in Canada, work and study.
6-When can apply for citizen ship?
You need 1095 days in Canada in a 4 year period to be able to apply for citizenship.
7- What finally you think will be the result ?
It depends on if you committed misrepresentation or not. If you lied about being in Canada when you weren't and they can prove this, then you are in trouble. If you didn't lie but you can not prove it, immigration may choose to believe you or they might not but I think they are unlikely to deport you in that case.
