If a Digimon has this card in its digivolution cards, does that mean that it isn't treated as "1 of your Digimon without [X Antibody] in its digivolution cards"?
That's correct. This card has a "Name: Also treated as [X Antibody]" rule, therefore a Digimon with this card in its digivolution cards isn't treated as "1 of your Digimon without [X Antibody] in its digivolution cards."

Does this card's inherited effect only activate if both [X Antibody] and a Digimon card are in the digivolution cards?
No, it activates even if only this card is in the digivolution cards.

If a Digimon with this card in its digivolution cards would be deleted other than by one of my effects, then an effect such as ＜Decoy (nocategory)＞ (When your opponent's effects would delete any of your other specified Digimon, by deleting this Digimon, 1 of those Digimon isn't deleted.) prevents it from being deleted, does this card's inherited effect activate?
Yes, it activates.

Can I use this card and then place this card in digivolution cards without digivolving 1 of my Digimon without [X Antibody] in its digivolution cards?
No, you can't. If digivolution isn't performed using this card's effect, you can't place this card in digivolution cards.
