What should I do to improve it, any online resources I should go for?
Can I name this kind of usage as unit of object? No
The list given in the site Gill provided a link to is fun, but some of these group nouns were made up for fun, and many of them are unknown to most native speakers - For example:shrewdness of apes, flange/congress of baboons,sleuth/sloth of bears.
You'll just have to note what people actually use.
Context is always important; labelling is rarely important.
