Close! Megumi fought a curse with Sukuna's finger. Those two brothers turned up to get it, and ended up fighting Yuji and Nobara. They got those flowery tattoos because of the blood technique. (I've rewatched season 1 a crazy amount, which is the only reason my memory of it is so good haha)

Also to answer your questions about domains, if someone activates their domain, you can activate yours and the one with the strongest domain occupies that space. S1E7 you see Gojo do it to jogo

For example, when Mechamaru destroyed his arm; it was said that Mahito didn't heal after it - he just changed the shape of his soul to pretend it healed; but he was still missing part of his soul overall. So if someone like Yuji keeps punching bits of his soul, there will be nothing left of Mahito to transform/recover.

Your question about Yuji/Mahito - Yuji doesn't have any techniques. He just has raw power and cursed energy. Mahito said that because there are two souls in Yuji's body, that Yuji is aware of the outline of his own soul; which I guess just means he's also aware of other people's souls and his cursed energy can attack them as well as their physical bodies.
Mahito's technique is being able to manipulate Souls, and then the physical body changes to match that Soul's shape; so if his Soul is damaged, he can't fully heal his body.

The guy with the thing over his nose is the older brother of the 2 half-curses/cursed womb people from the end of season 1. The ones with the corrosive blood. We seen him playing a game with Mahito and Geto while his brothers were being killed.
