Which programs can I uninstall from my HP Mini?

My laptop is running really slowly, and I think it might be because it has too much data. I know very little about computers, but I don't want to pay for someone to fix it if I don't have to. Below is a list of the programs currently installed. Which ones are safe to uninstall, and which ones should I keep? Please explain why I do or do not need the programs mentioned, if possible.
