I went through chapter 7 of the NLTK book looking for a solution to this but so far it unclear to me.
<NN>*means 0 or more of Nouns<NN.*>*as explained by the book means 0 or more nouns of any type
In NLTK are NN, NNS, NNP, NNPS exclusive of each other ? (I might be wrong in thinking that NN is an umbrella for the rest)
In that case does <NN.*>* mean that 0 or more of any of NN, NNS, NNP, NNPS which itself can be repeated 0 or more times(that outer *)? Or does it simply mean NN repeated 0 or more times which again repeats 0 or more times?
Or am I completely mistaken ?

Here's a list of the Penn treebank POS tags. As you'll see, NN does not encompass NNS, NNP, and NNPS; it only represents singular and mass nouns.
NN - Noun, singular or mass
NNS - Noun, plural
NNP - Proper noun, singular
NNPS - Proper noun, plural
<NN.*>* means any of NN, NNS, NNP, NNPS repeated 0 or more times (from the outer *), whereas <NN>* would mean only <NN> repeated 0 or more times.

Okay, so the internalNN.*in<NN.*>*just means one NN or NNS or NNP or NNPS, not many and then the outer * has the usual meaning. Is that correct? I mean the internal*, it is just a representative, it doesn't actually mean that something repeats 0 or more times (unlike the outer*). Is that correct?

Correct. The inner*is for repetitions of the.. Thus, that.*could match nothing,S,P, orPS, resulting inNN,NNS,NNP, andNNPStags respectively. The outer*is responsible for repetitions of the entire tag.
