You certainly can! HitFilm includes several advanced effects for creating your own lens flares and light effects.
Light flares are fully customizable and lens artefacts animate automatically as the flare is moved. Flares can even be linked to motion tracking data to create advanced animation. Both HitFilm Pro and HitFilm Express include standard Light Flares and Auto Light Flares, which identifies the brightest parts of your shot and applies realistic lens flares.
Various additiona effects for creating lighting effects are included in HitFilm Pro, and are available for purchase in add-on packs for HitFilm Express. Light rays & gleam create dynamic, volumetric lighting effects ideal for integrating composited elements with live action footage. Here's an unofficial tutorial showing one possible technique:
Light streaks simulate anamorphic aberrations, similar to the visual style of JJ Abrams.
Lens dirt generates realistic in-lens reflections and dirt specks which adds realism to any CG shot. See it in action 24 seconds into this video:
