Then the goldfish will die.

Technically , both require different environments. Goldfish likes cold water and angelfish likes tropical. However, goldfish can survive in warm water so both can be kept, leaving one of them unhappy.
When goldfish are large enough, they are called carp. Tilapia is not a goldfish or a carp, although the species does have some similarity.
No, first of all they should not be in the same tank, and secondly, goldfish are egg laying fish so they do not get pregnant
Angelfish are mainly insectivorous and carnivorous. Goldfish are mainly omnivorous and vegetarian. So you can see that their dietry requirements are different. The reason fish food manufacturers have gone to the trouble to develop and manufacture goldfish food as a separate product from other fish foods would indicate that there is a difference in their dietry requirements. So the answer is No! It is not OK.
No I'm afraid not. As goldfish grow bigger they eat whatever fits in their mouths. But the only species that mixes with goldfish is the weather loach.
Angel fish are semi aggressive fish. They may have a tendancy to pick on the gold fish. Also, angelfish need tropical warm water to survive. Gold fish like cold water. I would not put them together. If the Angel is big enough it will eat your goldfish.
