is combindely a word or you just say in combination or combined.
is updation a word or you just say updating.
Combindely, or any other attempt to add ly to combine is not an English word. I found combinatory and combinatorially but I wouldn't recommend using them. In combination and combined work just fine.
Update can be a noun or a verb, there is no need to add ...tion to make it a noun.
I saw an update on the approaching storm. We should update our warnings.
