Inertial force is not fictitious (partially reposted)　(クリ)

Gravity acts on everything equally. And if there is action, there is reaction. As stated by Newton's third law of motion. Below are some examples.
F = mg (free fall)
F = normal reaction
F = air resistance (falling at terminal speed)
F = air resistance + inertial force (falling before terminal speed)

Is F in F = mg fictitious ? The claim of fictitious will not hold.
