From the left to the right:

• First medal is the 1939-1945 Star.

• Second medal is the Atlantic Star.

• Third Star is the Africa Star with North Africa 1942-43 Clasp.

• Fourth Star is the Burma Star

• Fifth Medal is the Defense Medal

• Sixth medal is the War Medal of 1939-45

I'm having trouble finding the last one so I'll edit this if I find out what it is.

EDIT: Found the last one, it's the Long Service and Good Conduct Medal
