Repair plaster board in bedroom

I have a wall in a bedroom that has a little hole and some dents that I would like repaired. I'm not sure if the hole can be repaired or if new plasterboard/ gib over a section needs to be done. There is a little plastering I think needs doing also where some of the paint has rubbed off? I'm not too sure what is required sorry. I have no idea of the cost either.
