I looked around the Fitbit app but it looks like you can only change to a 24h clock if you log into your Fitbit dashboard on Fitbit.com. When you do so, click on the gear in the top right and then click on settings. Look for Clock Display Time under Advanced Settings. 

As for SpO2, you must track your sleep with your Charge 5 to get this info. After wearing it to bed for a few days, you will see it in the Health Metrics section of the app. As far as I know, you cannot get this information in real-time or on demand.

Let's go to the fitbit help docs for info on how to set the time or the 12/24 hour mode.
