Sure thing

Here are the graphs for each of them
S_Therapist
utlptc
Jrashid
pkmoney pkmoney is very odd itself it was dormant since its registration in Jan-13. Then it was active from Nov-13 to May-14 but slept again until May-18 (I guess that's when it was hacked and purchased). Then it remain active for three months only from May-18 to Jul-18 and it is silent since then.
Since we assume it was controlled by different people, so here are the two graphs for it's active periods of Nov-13 to May-14 and May-18 to Jul-18.
pkmoney -May-18 to Jul-18
pkmoney -Nov-13 to May-14 
For the comparison graph i tried but it was really odd since all these accounts were active in different dates. See below number posts per month from Dec-2017 to Jan 2019

You can see it was only month of Oct-18 when they all posted together except for pkmoney.
So I did compare the month of Oct-18, and here is the result. (Graph was very wide so I had to split it)
