2 ) i'm try to write about health and relationship/dating ..can i sell this kind of niche articles? or what other niche is hot to sell?

For your article writing, as long as it's above 300 words, it's a worthy article.

Secondly do not be limited by the number of words, as long as you can write and your content is useful and make good sense, just write.

Thirdly, do not write based on hot topic, write something that's of interest to you, in that way you can brand yourself to be an expert in that area, so next time if you come out with ebook, you can make good use of those credentials.
