British terms?

Do British people have names for all the things in this picture? And if so, what are they?

In America, #1 are called cookies, #2 are called crackers, #3 are also called cookies, and #4 are called biscuits (which are like scones, but not as sweet). If an American says they'll give you a cookie, you don't know whether they'll give you #1 or #3.
