They will be OK together provided you don't overcrowd them and overstock the tank. If you follow the basic rules of fishkeeping which are. :- 1 inch of fish needs at least 1 gallon of water. :- Every tank must have a permanently running filter. :- Every tank must have at least 50% of its water replaced every week.

Fail to look after the fishes water as above and I can guarantee that your fish will be constantly getting sick and will live a much shorter life than it should.

Yes! Because they are both livebearers, they are great tankmates for each other and can happily live in the same tank. Other good compatible tankmates would be swordtails and guppies, which are also livebearers. Livebearers tend to stick together and can be the perfect set up for a community aquarium.
Yes, i have them in the same tank and they're fine
Livebearing fish (including guppies, mollies, platies and swordtails) are notorious for eating their young, sometimes as they are being born. If it is possible to separate the mother into another tank immediately after birth of the young, it should be done.
What are guppies
They should never be in the same tank because Guppies are tropical fish and like to be kept over 70F and Goldfish are coldwater fish and like to be kept below 70F. So Goldfish should not bite guppies because they should never be in the same tank together...
