I honestly don't see what the confusion is. 0 is absence is the absence of that about which you are concerned. 1 is the thing or idea of unity (the unity makes it one idea or thing). Anything over that is ebrown said: multiple 1's.
I presume Frege meant that you could not linguistically or logically formulate the idea 'a set of one'. Indeed, I think he is right. The set 'a set of one' would seem to be one.
Also, consider the set 'the set of five cows'.
In this set, the cows are already counted, before the set was
formed. So the set is not a mathematical function for counting. The set 'a set of five cows' is a reference, a reference to a 'a count of five cows'.
