Answer 1

you can use this ([0-9]\.*)*[0-9] regex to get it. you can test any regex here

Edit

this sample code in C#

Regex regexpattern = new Regex(@"(([0-9]\.*)*[0-9])");
String test = @"Question 1 and Question 2.1.3";
foreach (Match match in regexpattern.Matches(test))
{
    String language = match.Groups[1].Value;
}
