Take a look at http://ark.gamepedia.com/Breeding#Times_for_Breeding
You will see that every dino has different times for hatching and maturation. Those times are affected by the multipliers, so it is not possible to have every dino grow up in 30 mins, because the base time is different.
For the options:
MatingIntervalMultiplier - affects how soon you can mate dinos again after mating. Base mating interval is 18:00-48:00 (random), apply the MatingIntervalMultiplier to get the new interval. E.g. a setting of MatingIntervalMultiplier=0.1 will result in a 1h48min - 4h48min intervall.
EggHatchSpeedMultiplier - as the name says, affects how quickly eggs will hatch. Again look at http://ark.gamepedia.com/Breeding#Times_for_Breeding, in the incubation section the time column will give you the hatch time for a dino, e.g. 5 hours for a rex. I have a setting of EggHatchSpeedMultiplier=10, which makes rexes hatch after 30 minutes.
BabyMatureSpeedMultiplier - affects how quickly babies will grow up. According to the breeding times, a rex will roughly take 92 hours. I have a setting of BabyMatureSpeedMultiplier=10 which makes it go ten times faster, resulting in a duration of roughly 9 hours.
For the other options, you can change the cuddle interval so you get imprinting bonuses more often - but they will have a smaller percentage. The default interval is a random value between 3 and 4 hours, and the % you get with each imprint is calculated as the max (4 hours) divided by the total maturation time. So decreasing the cuddle interval (= setting a value lower than 1, which is the default) makes care taking happen more often, but the % you get will get smaller.
There is a lot of math behind it, and it cannot be configured so that all dinos grow at the same speed. It will always be different. So best you pick a dino (e. g. rex), and think about the desired breeding/maturation times, and set the multipliers accordingly.
Hope this helps.
