The Feature Control Frame (rectangular box) contain the geometric characteristics symbol, and the form, runout or location tolerance. You can find more information on this PDF. The M within a circle stand for Maximum Material Condition (MMC)

"24x" means that the description is true for the 24 pins of the part.
