A is a tantalum capacitor
B are diodes. The code may be printed on the glass body
C and D are most likely capacitors.
F ... agree with Swake, good chance they're inductors.
The small rectangles with numbers on them are resistors ... last digit is the number of zeroes for example 101 means 1 zero after 10, so 100 ohm ... in your case 333 = 33000 or 33kOhm
I - small ceramic capacitors
E probably a film capacitor otherwise could be an inductor. probably some film capacitor with a very weird capacitance value to get a specific clock or frequency.
G could be anything, could be a transistor, could be a mosfet, could be a fixed voltage linear regulator, no idea. Numbers or code on it may tell you more.
