literature language

Here are 3 questions that I don't understand from "The scarlet letter":
1) ^{Chapter 12}
Pearl laughed, and attempted to pull away her hand. But the minister held it fast.
" A moment longer, my child!" said he

2) _{Still chapter 12}
Pearl mumbled something into his ear, that sounded, indeed, like human language, but was only such gibberish as children may be heard amusing themselves with, by the hour together.

3) ^{Chapter 13}
A species of general regard had ultimately grown up in reference to Hester Prynne

I don't understand the words in bold, please help
Thanks in advance
