Is that two stage vacuum pump?

Yes, the 1948121 is Two Stage Rotary Vane.

Can I use a 7 cfm vacuum pump on a car?

That's plenty for a car system...you can also use a smaller, less expensive 1 or 2cfm pump. 5 cfm and larger are for residential and commercial A/C systems.

What's ultimate vacuum this 12 cfm vacuum pump can pull in microns?

I walked away from it long enough to see it hit 293.

Can i use the 5 or 9 cfm on my freeze dryer? i need at least 150 or better mtorrs. and is it maintenance free or do i have to cange the mineral oil?

Oil needs to be changed occasionally when it becomes cloudy or discolored for better vacuum.
