Federal Agents have jurisdiction in EVERY STATE, so yeah. They can routinely be used to even assist state troopers when manpower is low or leads are few.
Before a Customs agent would make an arrest for a warrant of any type, the agent would have to believe the agency holding the warrant would come to the port of entry where the arrest was made to pick up the person with the warrant. If the agency is adjacent to the port of entry (e.g. a San Diego warrant in San Ysidro), this is likely. If the agency holding the warrant was distant to the port of entry, it's unlikely they will expend the time and money to fetch someone with a misdemeanor warrant.
Call your parole agent!
If the trafficking crosses state boundaries, it will be tried in the federal system. If not, it usually depends on whether a federal agent or a state agent performed the arrest and if you are being charged with a state statute or a federal code violation.
What you're describing is called "Padding" a file. It's not a common practice as it's not only illegal to do but can also open the agent to civil liability. These types of civil liabilities can be very costly (into the millions).
Parole Agents/Officers do not possess that power. Only judges and magistrates have the pwer to issue a warrant. However, the agent/officer can present an affidavit for a warrant to the court to support a request for the issuance of a warrant.
'Agent' can be many things, but if the person has DEA credentials or identification, it is most likely that they have arrest powers.
You become a fugitive from justice, and a warrant is issued for your arrest. Depending on the crime, bounty hunters may come after you... and law enforcement agencies are duty-bound to bring you in if they find you, in any case.
