You don't have to do them all. You can learn a lot by working with just a few of the roses.
The hips you have harvested are most likely to be selfs ... meaning the pollen probably came from the same plant rather than another rose.
I checked the descendents lists for the roses above.
No info on 'Old Blush' because parentage is unknown.
'Summer Snow' has 86 known descendents, but it is a sport of 'Summer Snow, Cl' which has 88 known descendents. 'Summer Snow, Cl' is a seedling of 'Tausendschön' which has 313 know descendents and is a seedling of 'Crimson Rambler' with 11,828 known descendents.
'Veilchenblau' has 201 known descendents.
'Debutante'. the floribunda by Warriner has no descendents, but Débutante by Walsh has 2 known descendents ... I'd probably pass on this one.
Poëma -- no descendents.... another pass
Thalia -- 6 descendents ... maybe another pass
'Robin Hood -- 10,766 descendents.
Go ahead and do a small experiment and see what you get.
Roseseek (Kim Rupert) is a rose breeder and processes more seeds than any of us who just want to experiment would ever think of processing.
He has listed some of his more interesting crosses on HMF. Several of his roses are in commerce and several more are being tested for introduction.
The list of crosses he made this year is mind-boggling. But don't let that intimidate you. He started out exactly the same way you are thinking of starting out and it became his passion.

A lot of amateurs have introduced roses that have stood the test of time. They all started with "I wonder what I would get if I planted the seeds from these few hips I have collected". The thing is, they had fun playing with the "I wonder ...." Many have never introduced the roses that came from their experiments, but who knows what
you will get ?
