Number in the ring is the ring counter. The smaller number right by the ring is the total uncollected rings (Excluding monitors and lost rings). The number below the counter is the score. The time appears below the score should a time limit be put in place. The X and number by the life icons are the amount of lives the character has. In the shown example: the entire Final Hope Trio is in a stage, and they have 9 lives left.
