To figure out your exposure times:
Take your focal length measurement (ie:2”) and divide it by your pinhole measurement (ie: .008”). This will give you your f/stop (ie: 250). You then go to your list of f/stops and find the one that is closest to your camera. In this case it would be f/240. You can now use a light meter to gage exposure times. If you don’t have a light meter, like myself, use the sunny 16 rule. I don’t want to go on about stuff you probably already know, but let me know if you have any more questions. Also, it is cheapest to shoot on RC paper (I just cut it down) until you get a feel for your camera. It is nice because you can shoot something and then come inside and develop immediately to know if you are hitting the right exposure. The speed of paper is roughly 6 so you just need to take that into account when calculating.Also, there is no viewfinder so to frame your shots you need to look at the angle that is created from the pinhole to where the film is. Does this make sense? I can make a little diagram if needed. Just let me know. Good luck!
