Hey, please suggest any tool which may help me to filter followers with less followers
Twitter doesn't let you filter your or any other followers according to the number of followers.
So you can use a third-party tool - Followeraudit.
Audit your profile with this tool and within few minutes a list of your followers will be published, you will be able to sort the followers in increasing or decreasing order according to the total number of followers, following and Tweet counts.
Sort your or any other public Twitter users followers and identify their most followed or least followed followers.
