You need no additional punctuation. They look fine as they are. When possible, you should have each quotation on a new line, but the example you give (inside parentheses) is OK.

The punctuation in this example is fine. You do not need a comma after the first “Yeah” since it is not in a series (There are only two quotations). Yes, the commas after the “he said/she said” statement before the opening quotation marks are placed correctly.

It looks pretty good.
