6)Put a keep out area-means gnd and vcc layer both or only gnd should not pass under this section

5) L3, L5, C12 and C10
6) Means nothing, not ground no routing:

7) Wow, many vias! Small ground islands should be grounded with more then one via. 4*4 vias in the center pad should be enough. Vias along the RF path is good, and vias close to the grounding pads of the components are good. 

Best regards,
Kaja
