Means the stiffness of the shaft. It is for slower swing speeds. However I tend to reverse that thinking. Rather than matching a shaft flex to benefit a swing speed I match shafts to prevent damage to a swing. Anyone can swing a stiff flex and suffer no real ill effects. The worst that can happen is that you are accurate and maybe a bit shorter (not much) However not everyone can use a whippy shaft flex. The balls will be sprayed all over the place. I bought a Driver on ebay that had an intermediate flex. I sprayed balls to the right and even got a slice back that I had not seen in years. After a few trips on the course it was enough of the intermediate flex. I removed it today and replaced it with a regular flex.
Different manufacturer's of golf clubs have different names for shafts of the same specs. RL is equivalent to; A flex, L Flex ( Light flex not Ladies) and the more commonly known seniors flex. These shafts are designed for a lower clubhead speed.
X flex means extra stiff. It is a flex for players with a swing speed of 105 mph or more. Most professionals would use this flex.

about a 40 flex is maximum for a junior stick ---------------------------------------- The biggest flex a hockey stick can have, and I'm assuming you mean the largest number, is a 115 to 120 (depending on the manufacturer). A 120 flex is fairly difficult to find and most are only available in Europe. For the most part, the highest flex available in the USA is a 110. In case there was any question, the higher the number in the flex rating, the stiffer the stick. Here is a listing of average flex ratings for each size stick: Youth - 35 to 40 flex Junior - 50 flex Intermediate - 60 to 70 flex Senior - 75 to 110
