Yes, guppies will eat their young. This is why you should separate the guppy fry from their parents and any other fish if you want to save the babies.
Yes
yes that is why people put plats to hide guppy babies
Well, Adult Guppy's Can't Eat Other Adult Guppy's. If The Guppy's Breed Then They Won't Eat Any Of The Guppy Baby's. They Will All Work Together To Take Care Of The Baby's. But If They Breed And You Add Another Guppy/Fish Then It May Eat The Baby's.
it might not eat it but it can bite it's tail or harm the fish

No, a guppy isn't a reptile. A guppy is a fish.
They can not eat live grown angel fish.
Many Fish don't eat guppies, like the neon fish. That is the most common mix I know.
