The test vectors listed in
Are represented as Hex strings? I'm sure that the key is, because it's length is 32. And each hex digit, nibble, is 4 bits. So 32x4=128. But what about the stream generated? How are they represented?

Yes. The stream is also in hexadecimal, as is the IV if used.
The representation is just the output stream broken into 64-byte sections. Some of the tests output 512 bytes of stream, some output 131072.
