"Are you sure you left it on the table?" asked Roberto. is the only correctly punctuated sentence here.
the first sentence requires a COMMA inside the quotations, rather than a period. "Judy said" is attached to the quote, because the quote is judy's words. you keep them together, rather than making them two separate sentences.
the third sentence is missing a comma as well. "oh no," sarah said... is the correct way to write it, with a comma after "no."
the fourth sentence is wrong for several reasons. your end punctuation goes inside your parentheses, and this sentence put the exclamation point after. "She laughed" additionally requires a period to end the sentence, stating that she laughed, then offering her dialogue. alternatively, you could place a comma after "laughed" and accept that for the verb leading into the quote.
