Could the Seven and Lester POTENTIALLY stop and beat the disaster curses? [all]

Conditions: All jj sorcerers are replaced by Percy, Jason, Annabeth, Piper, Hazel, Frank, Leo + Festus and Lester. No reinforcements. They can walk through and out of curtains and they have to beat the curses. Lester has his arrow of dodona, and the curses can be affected by charmspeak. There is a source of water nearby, and Percy doesn't have the curse of achilles.

SCENARIO 1: Percy/Jason gets sealed. The demigods' only goal is to unseal them.

SCENARIO 2: Piper and Jason face Mahito while Percy gets sealed.

SCENARIO 3: Percy and Annabeth face off Mahito with Jason sealed.

SCENARIO 4: Lester and Dagon fight.

SCENARIO 5: HAzel, Frank and Leo get winded up in Dagon's domain.

Who do u think wins in these scenarios and why? PS who just overall wins, the demigods or the disaster curse group
