Answer:
Yes.
Step-by-step explanation:
Consider the simple method for English in which affixes denote singular or plural status for nouns.
For example, -s and -es indicate plural, and in the absence of those affixes, the noun is singular.
Of course, there are exceptions, such as fish, deer, and sheep, to name just a few.
In those cases -- if you are truly excluding any (presumably verbal) context as you stated, then you could indicate quantity by using fingers.
