Q1: We have a situation where we have two face-up security cards. If I activate the On PlayWhen Digivolving effect of this card, do I De-Digivolve 2?

No, you do not De-Digivolve 2, but De-Digivolve 1 twice. When De-Digivolve 2 is played, the two cards on top of each other are considered to be trashed at the same time, but when De-Digivolve 1 is played twice, the cards on top of each other are trashed one by one. For example, when two cards are trashed from the top of a resting Digimon by De-Digivolve 2, the effect of the second "BT15-047 Kabuterimon" to be trashed is not activated, but when De-Digivolve 1 is performed twice, the first If the Digimon becomes "BT15-047 Kabuterimon" after trashing with the first De-Digivolve 1, it will not be trashed because it will not be affected by the second De-Digivolve 1.
