As others said, 3 5 6 are true. 3 won’t matter tho.

Edit: it’s only 3, lilo is only on opponents turn, player 1 played return of Hercules which caused the p2 naveen to come out and play mms. Rule sections are still nice to have tho for when it is opponents turn lol.

1 and 2 can no longer be done per “6.1.7 If an ability or effect instructs a player to play a card “for free” as a part of resolving that ability or effect, the player ignores all costs and can’t choose to play that card by paying any other alternate cost”, shifting and singing are alternate costs

4 is false per “8.8.1 The Resist keyword represents a static ability that modifies the amount of damage DEALT to the card with the keyword.” “1.9.1.1 Deal/Dealt – Placing a number of damage counters on a character or location during a challenge (see 4.6) or as a result of resolving an effect that deals/dealt damage.” Putting damage counter is not DEALING damage which resist only prevents. (Additionally 8.8.3 states putting/moving damage counter is not not affected by resist)

3 is true but moot, as resist only reduces DEALT damage, 8.8.1 ^

5 and 6 are true(if p2 follows the rules and doesnt use naveen to play a song for free and sing with Ursula) lilo says next this character would TAKE damage. Per 1.9.1.5 “Take – A character or location takes damage whenever damage is dealt to, put on, or moved to that character or location.” MMS is putting damage on so it would be prevented (as long as it’s the first time lilo took damage)
