I know some of the answers:

Functional defect is nothing but you find while you are doing functional testing

Performance issue nothing but while you do load/performance/stress testing. Ex: how long its taking to reach one web page to other web page

Usability issue: This will find in Manual testing and tester should look at application in detail and never skip any section. For example, gmail log in functionality: user able to find help links/buttons/registration for new user/forgot password/ forgot user name/ user able to read content on webpage/all text fields accepting data. simply How comfortable is developed application.
