Yes. I can't check the precision of your specific coordinates at the moment, but the principal is fine. Make sure to review your enemy and NPC jump ranges so they can navigate around the area. You will also want to give them (and players) walkoff animations so they don't look silly from tread-milling midair while descending the platforms.
Hmmm... something seems off from the wall settings there but I couldn't confirm it without the game though.
However, I could help you set wall settings if you gave me or post that panel here so I can use it to set walls.
