3. What is the difference between Slide Transition and Custom Animations?

Not positive but I believe a slide transition would be the effect the slide does to go to the next slide. And custom animations would be what the things you have on a particular slide does. Like you can animate some of the stuff you put on a slide, like you customize how (say you have writing on there) the writing comes onto the slide, then you can animate it like make it shake or something, then animate how it would leave the slide. So I think slide transition is how one slide goes to the next slide, and Custom animations are what the stuff on your slide does.
