You don't have to escape the exclamation mark:

testo = testo.replaceAll("!{1,3}", "! <br>");

Should do.

{1,3} means 1 to 3 consecutive occurrences.

Why do you need regex for this? You can simply do String#replace

testo = testo.replace("!", "! <br>");

However to remove multiple exclamation marks use:

testo = testo.replaceAll("!+", "! <br>");
