Is the panasonic lumix g 14 140mm f 3 5 5 6 ii good for portraits?

It's a reasonable portrait lens, but not a great one. On Micro Four Thirds it frames like 28-280mm on full frame, so the 85-135mm range that suits portraits on full frame lands around 42-70mm here. That's a comfortable range for head-and-shoulders shots and environmental portraits, and the optical stabilisation helps when you're shooting handheld.

The weak point is the f/3.5-5.6 maximum aperture. It won't blur backgrounds much, and it gets darker as you zoom in. For portraits, a faster lens will give you more of that soft, separated look, and the Portraits page explains why the lens matters more than the body. If you already own this lens, it will still do the job, especially at the wider end.

It fits many Micro Four Thirds bodies, including the OM System OM-5 and the Panasonic Lumix G85. For the focal length reasoning, see the Lenses guide.
