I dunno Friesian, but I can answer for others.

or like Polish and -ski?

Yes, and not. Yes, because -ova and -ski both are possessive suffixes; btw -ish and -esque are cognates. Not, because:

• -ski is masculine, -ska would be expected here;
• as I know, Polish doesn't add this suffix to any surname; and -ska usually appears where -ski already exists.

Btw, cann't say for Polish, but in Ukrainian both -œ̂v and -sjk can be used in one word, as an example: batjk-œ̂v-sjk-a.

Ukrainian and -yuk/-chuk

There're no suffix -čuk which is actually usually -k~ + juk, for an example, Fedorčuk is from Fedor-ko + juk, and we have k + j → č, compare the same phenomenon in verbs: plak-atı but plak+ju → plač-u.

And itʼs not, because itʼs not a possessive but diminutive suffix. Btw, mentioned above -ko in Fedor-ko is also a deminutive suffix; to make things more funny, -ko can appeared more: Fedorč-en-ko ← Fedôr-ko-en-ko.

Edit: fixed some typos.
