How to custom excerpt?

You can explode the content of excerpt by dot.
For example:

$text = "Morbi consequat tempor augue. Nec fringilla eros auctor scelerisque. Etiam in ullamcorper tellus. Sed ac dui rutrum.";
$pieces = explode(".", $text);
echo $pieces[1]; // get second sentence = Nec fringilla eros auctor scelerisque

Maybe this can help you.
