So I have this closed loop system H and I've plotted it's bode plots, magnitude, and step response. From these plots, how do I find information about this system such as Tr,Ts,Tp,Mp,Wm,Wb,Mm, and steady state error?
Is there a function similar to stepinfo(H) that I can use to get information from this plot?

I have no idea what your parameter abbreviations mean, since they are not completely standardized.
There are a number of Control System Toolbox and System Identification Toolbox functions that will yield various characteristics of your system.
See Time and Frequency Domain Analysis (link) for descriptions and links to them, the dcgain (link) function being one.
