This page refers to the adult, Osomatsu-San version of Jyushimatsu. Click here for the Osomatsu-Kun version, where the Matsuno sextuplets are 10-year-old fifth graders instead of NEETs.Jyushimatsu Matsuno is the fifth son of the Matsuno sextuplets.
Canon!Matsu and Place!Matsu are practically identical, so there is no need to compare and contrast them.
To learn more about the Osomatsu-San timeline, just watch the anime. There are around 25 canonical episodes, along with a few bonus ones, such as Episode 3.5, which you can find in the above link, along with Episode 26 (which has been rewritten under Osomatsu's request).
