the rest

The words "the rest" refers to other believers that the Jews brought before the officials.

they took security ... they let them go

"the officials took security ... let Jason and the other believers go"

took security

Jason and the others gave the money to the officials to show that they would not cause any more trouble. This was not a fine or a punishment, so they might have expected the officials to give the money back later.
