No, not necessarily. It depends on who is using the symbols.
From what I gather, the first symbol is Odin’s Horn, or Odin’s Moon, or something of the sort. I’m not too familiar with it but that’s what I got from Google.
The second symbol is called a Triquetra and comes from Celtic regions thousands of years ago. Historians aren’t sure exactly what it means but since it never* showed up in compositions on it’s own, they believe it wasn’t a main symbol used for worship or religion.
*never as far as they have discovered yet
The third symbol is more modern, if I remember right. It symbolizes the three phases of the moon and is used in Wiccan belief systems. Solitary witches use it as well if it’s one they connect with. This symbolizes the moon phases, as I said, but also the phases of The Goddess within Wicca as Maiden, Mother, and Crone.
The definitely don’t all mean the same thing. I can’t speak for the first one as I have absolutely limited knowledge on Norse belief systems. However, the Triquetra coming from Celtic lands as far back as 5000 years makes me, personally, tie it to Celtic beliefs specifically. My explanation of the Triquetra is that each point represents one of the Celtic realms: Land, Sea, or Sky. The circle the surrounds them all shows that we are encompassed within all of them yet the realms are also separate.
I hope that was helpful!
