Many people in this world have love, love is an extraordinary feeling that each people feels for another person.
"each people" is wrong. People means a collection of men/women and therefore it is a plural word. So it should be "each person".
Also, I like if you changed the first part of this sentence. For me. it does not make much sense. You may say;
Everybody needs love to enjoy life. Love is an extraordinary feeling that can heel many wounds be them physical or emotional. It is a very pleasing experience that provides people with great enjoyment.Also with love we can do best things in our lives, for example the love that parents feel about their sons and daughters it's a free thing.
What do you mean by "free thing"? Also, what's the connection between the first and the second parts of your sentence? If you say that love helps people to do their best, then your example should support that point.
