Can we be certain whether it was drawn in a simulator? It has several markings and notations which suggest it was done in a drawing program for electronics.
In any case a simulator is able to calculate for 3 transistors/ mosfets the same way it does for one transistor. It may take longer to run since it is more complicated. And it's easy to make mistakes when drawing it, causing more errors. These have to be identified and corrected. And there are times you need to use a handy trick so the simulator doesn't hang.
for Q4 why it dosn't has dc-block capacitor?Q4 use L8 and C27 as output matching network
why we can't named c22 as dc-block capacitor for coupling two stages amplifier?Q3 use L7 and C22 as output matching network
You may name C22 a DC block capacitor.
There are a lot of papers and books available on the net for PA impedance matching. Just search for them.
