I am writing my own implementation of a local planner which generates 7 trajectories and choose one of them. I want to display all the 7 trajectories on rviz each time the local planner is invoked along with the trajectory chosen with a different colour. How to do it in ROS ?

This is what Markers are made for. The Tutorial on Points and Lines should be a good stating point, as it is pretty similar to your application.

You could use a single MarkerArray Topic for this. Within a MarkerArray, a marker is identified (e.g. when it comes to deleting or updating) by it's namespace and id. So you could create a namespace for each trajectory (e.g. just '1', '2',...) and set the id according to the position of a pose in the trajectory. The single marker could then be of type Arrow .
