Can the film be cut and used for multiple smaller windows?

Can this be removed easily?

Yes however it may peel some of the paint with the tape.

what is the R value of the film?

R value of less than 1. The purpose of the film is not insulative R value. The purpose of the film is to stop air movement (drafts). It works great over the large two section window where we installed it.
