A nitpick is that [2] isn't front running. Front running is where you figure an institution is going to buy lots of some stock and get a buy order of your own in first, typically done by brokers.
Making fake trades to make the price look like it's going up can be called market manipulation in this case I think. This is also called painting the tape. A similar but slightly different scheme is wash trading where you basically sell an asset to yourself to make it look like that's the price and that there is trading volume going on. There's a lot of this kind of thing going on with NFTs.
