No. There is no requirement in the law that officers must have their hats on when they pull you over. Many departments have internal "wearing of the uniform" guidelines that specify when they would like you to wear a hat to present a neat and professional appearance, but it is not a legal requirement.
It depends on state law. In the state where I live, it is legal to have a police badge as long as it is for collecting purposes only. Using a police badge for any other purpose such as impersonating an officer is illegal in federal and state law.
The Order of the Arrow (OA) is a national honor society within the Boy Scouts of America, recognizing Scouts who exemplify the Scout Oath and Law in their daily lives. While there isn't a specific merit badge for the OA, members can earn the "OA Service" award through participation in OA activities. The organization promotes leadership, service to others, and the appreciation of the outdoors, often engaging in community service projects and camping experiences. Membership is by invitation, based on Scout spirit and achievement.
A minimal requirement for morality.
I doubt that it is a requirement of law that they must (although that may depend on your state law) - however - it may be a requirement of your employer - it may be a requirement of the bank or actuarial company that administers the pension plan - it may (possibly) be a requirement of your states law. If the answer is impiortant to you, you should consult with someone IN YOUR STATE who is knowledgeable about such things.
No

Yes, a security guard can wear a badge, but it typically depends on the regulations of the security company they work for and local laws. The badge may signify their authority and role in maintaining security. However, it is important that the badge does not resemble law enforcement badges to avoid confusion or misrepresentation.
To sum it up in a few short words. Can not wear a badge in combination with a uniform that resembles style color local law enforcement. Can not wear a badge and affiliate with any federal or state law enforcement. Can not wear a badge and carry a firearm without proper license/permit. Other than that, it is legal to own, sell and wear if not identifying a private security affiliation.
