1. ^[a-zA-Z0-9]+([_.-]?[a-zA-Z0-9]+)?@[a-zA-Z0-9]+([_-]?[a-zA-Z0-9]+)*([.]{1})[a-zA-Z0-9]+([.]?[a-zA-Z0-9]+)*$

2. ^[^<>&~\s^%A-Za-z\\][^A-Za-z%^\\<>]{1,25}$

The first one is testing for an email address. To work out the second, google regular expressions.

It is worded a bit too much like a school question to be a bet.
