Need help with Countif function

Hello everyone! Merry Christmas!

I am a complete newbie and would like to ask for help with my worksheet. I am trying to count all positions according to the shift (days - tw, evenings - tw, or in office). I am able to get the correct countif function when all the data are arranged vertically, however, mine has data in multiple columns and i cant figure out how i can do the countif with multiple parameters and multiple columns. The sample data attached has the explanation on what summary i would like to have. Really appreciate if you could help me with my file.

Thank you so much in advance!
