A skew chisel, a 3/8" spindle gouge, a 3/8th bowl gouge, a 3/4" roughing gouge and a parting tool. If they come your way singly, fine - it can be an advantage not have identical handles.
Turning tools are expensive - there isn't really much getting away from this. I would suggest avoiding cheap sets made of rubbishy steel. I had a go with a friends Sorby set recently and it was really good. Nice to use and a sensible selection (almost identical to what Phil suggested above!).
Twice the price of unbranded junk from Amazon / Temu, but holds a decent edge and you won't want to throw it away a month later.
Buying individually can made sense. I started with just a roughing gouge and bought unhandled tools as I went along. Saves money, instant use projects to practice on and easy to tell apart!
Have a think about what you want to make. No point buying loads of skews and other spindle tools if you only want to make bowls.
Also, it is surprising how few tool you actually need (and how many we all end up buying over the years...)
Don't waste your money on a big set, you can start out with just a bowl gouge and parting tool if that's all you can afford to start then over time you buy extra tools, alternatively keep an eye out for 2nd hand sets for sale.
