Saliva could: Saliva could kill sperm (pretty much anything could kill sperm). Haven't seen any research studies on saliva and sperm. Such research would be hard to make sense of, because there would be too many variables, such as: how much saliva, how many sperm, how much semen, how long in the saliva, etc... There will always be unknowns in life, except for the fact that life can be full of surprises.

Probably much shorter than that because saliva has spermicide activity.

My boyfriend and I are trying to have a baby via "turkey baster" method. If he ejaculates in my mouth, will saliva kill his sperm before I inject it?

Probably: If you're trying to have a baby, then why use this method to conceive? You have a better chance of conceiving if you cut out the "middleman".

Is it possible for sperm to swim through my girlfriends saliva that contains pre ejaculation fluid (precum) which was on my testicle.. and swim into my girlfriends vagina if she rubbed her vagina on my testicle?

Not a chance. You'll need actual intercourse to result in pregnancy.
