Yes. As a parolee, you have limited rights. A condition of your parole is to allow searches. Sorry
yes any room in the residence can be searched if the parolee has reasonable access to it. If your room is locked and your room mate does not have a key then the parole officer can not search the room.
Yes
Everywhere. He has full authority over the parolee.
Generally, yes. But be wary of harrassment. YEP... As a parolee you lose your rights to privacy in your residence. A parole officer can do unscheduled searches without warrants at any time to make sure you are following the rules. It is a condition that you agree to when you go on parole. Know that a regular officer is sometimes with the parole officer when they search, but the regular officer cannot participate in the search though. If a regular officer participates in the search anything he/she finds may be thrown out because the right to search only extends to the parole/probation officer.
The parolee signed a waver of rights when he met his parole officer for the first time. Essentially, in order to stay free, the parolee is made to give the parole officer that right.
You may send any correspondence "Care Of" the parole office to which the parolee reports. His parole officer will see that the mail is received.

No. A search warrant can be executed regardless of whether anyone is at home or not.
If you have lost your SBI parole number, you can get the number from your parole officer. Depending on your state, you might also be able to search for your number using your name.
The answer to this all depends on the specific conditions of the parole agreement. If it states in the agreement that only the parole agent (if agent is the only one listed) can conduct monthly home searches, then the officer cannot conduct a search unless the homeowner consents to the search. It likely says in the agreement that the parole agency, any law enforcement officer, and/or anyone it also would choose can conduct a search. Read the Agreement! It is a legally binding contract that was mutually agreed to by the multiple parties involved in it.
There is no consent needed from anybody when there is a valid search warrant in play. The court gives the police the right to search by granting the search warrant.
ADDED: Sorry, but the other answer is not totally correct. There is no "allowing" about it. With 'probable cause' the police may search you at any time without anyone's permission. You need to review your parole agreement, but it is likely that he can allow others to search whether or not he is there.
