Can rate limits can be changed?


I used streaming API downloaded lots of tweets, now, i need to check their’s retweet statues, i uesd REST API 1.1/statuses/show to access each tweet to check that, but the rate limits only allowed 180 requests per window.
I have more than 1000 tweets, how can i check all of them at one time? Can i change rate limits or can i change my code to run several times to finish it.(I use PHP).
Thank you.
