Hmm... much the same aperture as my refractor and not a lot smaller than your 5" - I'd say these will give you much the same as what you see with your 5" if you use the right eyepiece to give 30X, probably something in the range 25-40mm. Magnificent for trawling the Milky Way in dark skies and good for comets.
But for planets, you need both more aperture and a lot more magnification - which means a much longer focal length than binoculars have.
As for galaxies these are way too small - there is no substitute for aperture and 20cm is the minimum, at 30cm aperture you'll start to see interesting things.
I'd suggest a modest Dob would be a better choice - 20-25 cm, easy to set up, easy and comfortable to use and best of all, able to give much better views of planets and galaxies than the binoculars.
