Drying/dessication can be the death knell for seed embryos in pawpaw seed and acorns. They need cold, moist stratification over winter. If yours have been sitting at room temp/humidity for 4-8 weeks, as I presume, they may no longer be viable.
Best bet will be to soak them for a couple of days, then put 'em to bed in the fridge with some moist peat or sawdust and hope for some to germinate, but don't get your hopes up.
Cherry & peach, I can't help you with - but mmost peach seedlilngs are pretty decent, with regard to fruit quality.

I stick seed straight into the outdoor soil I want them to grow in- the sooner after eating the fruit the better. Let winter take care of stratification. Keep track of where you put them and the area weeded once they begin to sprout.
