Yes for all these. As long as your referee has magic shops for the ring.
Not even close.
“SPIDER CLIMB
2nd-level transmutation
Casting Time: 1 action
Range: Touch
Components: V, S, M (a drop of bitumen and a spider)
Duration: Concentration, up to 1 hour
Until the spell ends, one willing creature you touch gains the ability to move up, down, and across vertical surfaces and upside down along ceilings, while leaving its hands free. The target also gains a climbing speed equal to its walking speed.”
For one hour you have upside down, hands free, climbing speed. Athletics cannot get anywhere close to that. It’s like saying a mountain climber beats Spider-Man at climbing.
Pretty much.
