Is thi compatible with M12x1.50 Hex size 21mm.?

I’ll just be honest I didn’t receive the tool that comes with product but the dual fitting should be 19mm and 21mm as a standard.

Those lug nut wont rust inside&outside?

Use anti seize or if you're cheap use "clean" axle grease. Torque to specs (actually use a torque wrench).

Will they fit on s 2008 honda accord?

The lug nuts will fit the car, but you need to make sure an acorn style lug nut will fit the wheel you are putting on

What is the overall diameter of the nut

Regular diameter of any lug nut. However I don't recommend them because the inner cavity the key goes into, stretches and rounds out within 1-2 times of torquing them. I sent these back and just bought some quality gorilla lug nuts
