Forgiving someone for stealing money

Q: I'm an 18 year old female and I used to buy lots of personal stuff, for example, an expensive keyboard and mouse, a pair of headphones etc. but I bought these items using the money I stole from my father's wallet without his knowledge and might have stolen some from my mother's purse too. I felt guilty about my deeds later on and I stopped stealing like that and I also told my dad that I stole his money to buy things for myself. He understood the topic and he said he forgave me.

Now first of all, are all the things that I bought using my dads stolen money haraam for me to touch or use ? Even after he forgave me? Do I stop using these stuff? Some of the stuff are actually important for me to use. Do I have to return these goods to my parents? I bought makeup using the stolen money. Do I have to return that to my dad or do I have to pay him the amount that I stole? I estimated it around 600 USD (I didnt steal it in a day of course. It came up to that number day by day). I dont even have a job that I can earn that money and pay him back.

Secondly, the items are (as far as I remember) - a keyboard, a mouse and mouse pad, headphones for gaming, TONS of makeup (like alot), some dresses and accessories, ingredients for making D-I-Y lip balms (like oils and beeswaxes etc.) and empty tin and plastic containers (a LOT of these containers). Do I throw all these items away? Even after I've asked for forgivenesss from my mum and dad?

Thirdly, I also bought some gifts and stationaries with the stolen money from my parents. and the people whom I gave the gifts to, does the items become haraam for them to use and are they unintentionally committing sin because of me?
