Dear Monirul,

You should consider watching the introduction to parallel FreeFEM by professor Pierre Jolivet on youtube in the following link:
FreeFemTutorial

It’ll certainly answer your questions.

Best regards.

Yes, use the prompt command to run your codes as shown in the tutorial. I don’t know which text editor he uses in the video, it’s not really relevant. You may try vs code, it offers a freefem package.

Best regards
