any suggestions?
Thank you

Are you shooting raw or jpeg?
Can you post a resized example with EXIF intact?

That's iso3200 which is not relatively low. It is a dark scene which is more prone to noise, if you lift the shadows then you will intoduce more. I suspect what you are seeing is completely normal.
You can see some of my photos here if you are so inclined

Same comment applies.

Agreed ... underexposed and ISO3200 = noise.

Expose to the right (although I found the K-5II normally overexposed anyway), use a bit of flash ... or wait until the end of the year for full frame.

Take such photos at 1/30th of a second, or lower if you have a steady hand. problem solved.

The K-5 has remarkably little noise, and I happily use it up to ISO 1600 without any trouble, albeit it usually in good light levels.

In low light levels, the answer is a truly low ISO (say up to ISO 200) and a long exposure with the camera firmly on a tripod. If you shoot JPEG the camera will sort out noise reduction, and you can adjust the parameters for this in the menus.

If you are shooting RAW then there may well be noise reduction in the RAW converter, or you might use stand alone software.

Hope that helps.
Best regards, John

With a focal length of 700mm or more (in the sample photos), you must have an extremely steady hand.

I wonder what is going on with that

Sorry, I hadn't seen the extremely long focal length used. I'd say 1/100th is challenging and presumably the aperture the widest available.

Somehow I don't think it is really a 700mm f4.
