Does this support all regex syntax?

The generator supports the most common JavaScript regex constructs: character classes ([a-z]), quantifiers (*, +, ?, {n,m}), alternation (a|b), groups, and common shorthand classes (\d, \w, \s). Very complex nested lookaheads or conditionals may not be supported.

Can I use this to generate realistic test emails?

Yes — use a pattern like [a-z]{5,10}@[a-z]{4,8}\.(com|net|org) to generate realistic-format (but fictional) email addresses for use in testing and seeding databases.
