Can I ask in every post for getting some merits from people at the end of the post line?
You need to read forum rules:

You will see there that each member is not allowed to begging.
7. No begging.
I made a post today and two replies but no one get me the only one merit.
Don't worry about merit if you have good posts. Merit sources will find out your posts if they deserve for merits. Or people who have sMerit will appreciate your posts once they think your posts are informative, helpful, and quality. You just need to make posts more and continuously. Regarding your previous posts, if you got no single merit from them, it means those are not meritable.
