If i will post the same rss to 20 account is it ok ?

NO its not ok. Its definitely spamming and will get your accounts flagged or banned, how about use it for your advantage.

Tweet from your main account and then retweet that tweet from your other accounts. It makes the tweet viral while it expands the views as well!
