What are these rings?

[Shittenshite]

I found these rings in a car park earlier today and want to return them to their owner if possible.

What are they? Does anyone know what the inscription might be or mean?

Just fashion rings I think

They are very much like the kind of rings my 17 year old would wear. He has a spinning ring that looks like that

It won’t let me copy a link to the middle one but is in the style of Norse Viking symbols and is available on Amazon.

Thank you so much! I'm comforted that they're not valuable but I realise they may have sentimental value so I shall still attempt to reunite them if their owner wants them back.
