It's not very clear I guess but those are the stats you upgrade, in order, attack, stun, time and regen, then the number of orbs you have at that moment, which is useless to count since you're supposed to spend them anyway, and at the end how many diary pages you have collected which I guess you already knew that one.
Honestly is kind of pointless to show those stats there but I thought it was cool, like a JRPG save slot, playtime and diary pages are the only useful information.
