No all of them are not in spec...3&4 are low not in spec (if they were why is 1&2 so high/normal) were's the loss at... A leak down test will help determine were the loss is... You and most get caught up with the advertised min. spec,,, if all were 90/95 you would assume all were evenly worn but why are 3&4 so far off...
Lets say it was ran hot and scored the rings,pistons and walls all the cyl. had 90 would you assume cuzz you had min spec's it would be OK to move on with life...

A leak down will tell ya were the compression loss is it will not tell much about the oil control rings but that can not be determined yet... So why are 3&4 so far off... Read on about cylinder leakage... 20% is the line drawn for severely worn engine if all the valves seal and show no valve leakage... If you use 115 as a # for a engine in top notch condition and divide it by 10 you get 11.5,,,, 11.5 X 2 = 93 so I would consider a 93 compression number if all the valves seal to be a severely worn engine that has something to do with the rings, pistons are cylinder walls... You will have to de a leakage test to figger this out... NO ONE can tell you by a compression test alone why 3&4 are so far off other than a guess....
