How do I generate a random number between min and max?

1. I only have information on the minimum, maximum and median values. Can this be used to generate random numbers that satisfy a normal distribution?

2. There is only information on the minimum, maximum, and median values ​​of PMA, WT, and SCR, respectively. Each random number is generated and used as a value for one patient. However, there seems to be a correlation of PMA, WT and SCR. Is it possible to generate a random number that satisfies all of the above conditions in the absence of information about correlation?

i have no idea
