Everyone just kind of ignores it, I guess. I roleplayed Hiccup once, and I assumed that he would know a variety of languages (like in the books). I always pin Guardian/immortal spirit magic on Jack. Merida...this is tricky, she could have spoken Gaelic, but there is a minority language in the general Scotland area called Early Scots that looks like very, very rough Old English. Rapunzel was intended to be a Germanic kingdom, as specified by Disney themselves, so she could have spoken anything from German to Dutch to Middle English. Middle English, interestingly enough, is a form of Old English and has roots in Icelandic/Scandinavian/Nordic languages, and Early Scots is also descended from Old English.

tl;dr, Jack can understand anyone, Rapunzel probably could have communicated with Hiccup easily and with Merida with some difficulty, and Hiccup and Merida may be able to understand one another, though it doesn't seem likely. If you're a stickler for historical detail.

But like I said, everyone ignores the language barrier because it causes too much historical error and really, they shouldn't be able to meet in the first place (Hiccup & Merida: 10-12th century, Rapunzel: 17th century, Jack: 18th century--21st century). So it's just kind of like "What the heck, we can push the suspension of disbelief a little bit more."
