  Where can I find how many processes and GPGPUs my ansys, Fluent has?
  If input wrong number will program notify me and can this be reason for program to not respond?

  On start up or during a pause in a run?
  On start up you set the process count, and you should then see an error if you try and use more than your licence permits. Note it is possible to launch 8 cores parallel on a 4 core machine, and it won't help performance. GPUs behave differently, and unless you're using the new GPU solver I'd leave those alone for now.
  During a pause in a run, check the options under the Parallel tab (top ribbon) and I think it's listed in the Load Balancing menu.

  Yes and no. The LM will show what's being used, but I'm not sure if it'll tell you how many you're using (ie itemised list) as opposed to total for everyone.

  The licence file is wherever you put it, or where IT put it on the system. You're looking for a line something like
  INCREMENT aa_a_hpc ansyslrnd
  Unless you're using Ansys Student, which is covered here https://www.ansys.com/academic/students/ansys-student
