Stripes -
2 stripes are more than 1... 3 are more than 2, and 4 are more than 3 stripes.
So... what is the question...? All airlines have different policies.

The origin of stripes (and ranks) goes back to merchant marine uniforms.
As an example, PanAm wore uniforms easy to confuse with US Navy uniforms.
4 stripes for captains (or first officers qualified with captain type rating).
3 stripes for first officers. 2 stripes for second officers (cruise co-pilots).
Flight engineers had 3 stripes, two "wide" stripes and a narrow stripe.
Various combinations - and policies did change too.

I personally called "captain" any pilot with 4 stripes.
Some chief pilots or check captains had a "star" above their 4 stripes.

Ranks are never a problem, EXCEPT when operating at remote locations.
If you try (say as 2 striper) to get assistance on ramp from a local agent with 3 stripes.
Some areas (Africa-Asia-So.America) had that problem. They ignored your requests.
So a good idea was to send your F/E around the plane on ramp and him borrow your 4 stripes.
Was the only way to get the attention from some of these rampers.

In some nations, "basic training" of airline staff is "you have more stripes, so you are the top guy"...!
