Hello @ishi1234 ,
AJO provide out of box journey report as shown in below screenshot.

Live report: Live report to measure and visualize in real-time the impact and performances of your journeys and your messages
Live report | Adobe Journey Optimizer
Global report: Global report to measure the impact of your journeys and deliveries over a selected time period
Global report | Adobe Journey Optimizer
I think, you can not do any customization in this out of the box reporting. But it will provide most of the information which is required.
Thanks,
Parvesh
