My brother played tf2 on my account and now I dont know what to do with all those items! Need Help.

So here are all the items I currently own.

Is there something I can do with this items? Are they worth something atleast? Can I sell them?

I had no experience with tf2 so please dont blame me...

I play csgo so if theres a way to exchange this items for csgo items I'd definitely do that.
