Badly worded question. Law Enforcement does not need any special permission to conduct undercover operations. If that's not what was being asked - re-word the question and try it again.
An undercover cop is one whose identity isn't displayed. They try to dress like those around them so they don't stick out. An undercover cop may be involved in a stake out or could even be a detective.
Yes.

Yes
When the person named in the warrant is arrested, he will be held without bail.
Yes your furniture can be repossesed without a warrant, but those who are repossesing your furniture must have permission from a owner or guardian of the house to be in the house.
Only if you let them. If they don't have any warrant, they can only search you IF they have your permission.
Yes. Anythig that has been 'discarded' is considered to be trash and can be lawfully seized, searched, or impounded without a warrant. .
A warrant is an order for an arrest issued by the court. But many arrests do not need a warrant. If you punch someone in the face, and police are called, you will be arrested without a warrant, and one will not be needed. If say, you failed to show up in court, then a warrant for your arrest will be issued, to alert all officers that you should be arrested on sight. So the warrant itself is not the thing 'allowing' you to be arrested.
Items in plain view can be seized without obtaining a search warrant.
