What does the Flagger sign mean?
The Flagger sign (MUTCD W20-7) is a work zone sign under the federal Manual on Uniform Traffic Control Devices, the national standard the states build from. Someone with a STOP/SLOW paddle is working the traffic past this point, and what the paddle shows outranks every sign and signal around it.

What a diamond means. A warning. It tells you what the road does next and obliges you to do nothing in particular, which is the distinction test writers probe most often.
What orange means. Temporary traffic control. A work zone, and usually a higher fine.
Work zone signs. Orange is temporary by definition, used only while traffic is being routed around a job. The shapes repeat from the permanent set; what changes is the color and, in most states, the size of the fine.
What is the Flagger sign often mistaken for?
The Workers sign (W21-1). Only the flagger directs traffic; the flagger's STOP/SLOW paddle (W20-8) carries the actual instruction.
