The game is telling you several areas, End of Stroke switch is probably too close together and needs to be properly set - this is on your left flipper underneath the pf, you will see arms with metal "dots" on them, these need to be calibrated a certain way - but I'm also a newbie so not sure but you can look up flipper gaps on Pinside.
Next one sounds like a drop target to spell Adventure? (I'm not familiar with this game). Again, check the switch that activates to tell the computer it has been hit, may be the same thing with alignment of leaf blades - if this is a pressure target and not a drop target.
Left ramp will have a switch on it that tells the computer the ball has traveled across that ramp. Check that, it's like a small metal arm.
Last is a set of drop targets it looks like, you need to check the coil that is beneath those banks of targets as well as the switch (maybe an opto?) that indicates target is down or needs to be reset up, etc.
There is a switch blade test that you use to manually push on the switches and make sure that they register properly, usually makes a sound and the switch number appears on the DMD screen. If nothing happens when you push the switch closed, the switch is bad and can be replaced.
