X Antibody

Q1: 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."

Q2: 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.

Q3: 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}} prevents it from being deleted, does this card's inherited effect activate?

Yes, it activates.

Q4: 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.
