Which adjective form should I use, admirable or admired organisation? If my client wants to say that the vision of her organization is "people in the community will admire her organization the most in 2020", what should I say between "the most "admired VS admirable" organization in 2020"?

Each article or each one article or something else? I am writing a report and I want to say that "sixteen articles were from Canada, one article was from England, one was from Ghana, one was from Sweden, one was from Lebanon and one was from Pakistan." But, I think the sentence is really redundant or clumsy. Could I say ""sixteen articles were from Canada, (each) one article was from England, Ghana, Sweden, Lebanon and Pakistan". or what else do you recommend?

valued or valuable In the article I'm reading it says "... feeling like a valued member of the team, ..." Has "valued" got the same meaning as "valuable"?, I wonder. When I look up in the dictionary, it says "valued" means considered to be important or beneficial or cherished. Can I use valued and valuable interchangably?

Can "collaborative" be a noun? I'm reading an article with the heading "Building motivation to participate in a quality improvement collaborative in NHS hospital trusts in SE England: a qualitative participatory evaluation". In this paper, it seems like they always use "collaborative" as a noun. For example, "Collaboratives maybe an important way of engaging practitioners in quality improvement initiative." and "Quality improvement collaboratives in healthcare bring together groups of health professionals,....." Then, I'm confused what part of speech collaborative exactly is. As I look up in the Oxford and Cambridge dictionaries, they says that "collaborative is an adjective and is used before a noun. Can we use "collaborative as a noun like in this paper? and if we can why isn't it said in the standard dictionaries?
