Guppies are community fish that should never be kept alone or in bowls they require large tank, at least 10 gallons.
Yes they can, but they need natural food for a longer life.
Fish that have long, wavy fins should not be put with guppies, because guppies will nibble their long fins. Also, many bigger fish will eat guppies. Keep a separate tank with guppies and a few "cleaner" fish, which do not harm guppies.
Catch them with a net.

You may awnt to put her in a separate tank or a breeder box. Make sure the tank is a good temperature and clean. Of course, give her food. Take out of wherever she is and put her with the other guppies as soon as the babies are born. The other guppies will eat the babies as will the mom.
You can't place them down. You can only drink out of bowls, throw out bowls,craft bowls, place bowls in and out of item frames and put bowls in and out of chests. You might be thinking of a pot.
No Guppies are not moss eaters.
