In the first scenario you listed, the question would be fine since you are using a different team than the previous question.
e.g. What attack to use for Heracross? (Team of Electivire, Skarmory, Hawlucha, Gallade, Sneasel) vs. What attack to use for Heracross? (team of Escavalier, Cobalion, Infernape, Talonflame, Dunsparce)
^ This would be fine since you are using a different team and the circumstances will be different.
Also this is for ingame team questions.
Here's the clincher; ingame team questions are not allowed unless it is a Battle Spot or Battle Maison team. The question will most likely be hidden.
