Taffyta is the name of one of the characters, which probably means that they were fans of hers. They're most likely strawberry/vanilla hard candy lollipops. The heart faces may also be part of a wrapper and not the actual candy. Anyways, not real candies and not a real brand, though you can likely find something similar in a candy shop if that's what you want, like this: [link]
The little red things are, what I remember to be, hard candy. They're actually really small, like the size of five dimes stacked together and they taste like any other sweet candy. But judging from the name of the box, the creators were envisioning them to be like taffy.
