Well, the red one could be a lot of different roses -- there are a ton of red roses out there and your best bet would be to dig around in the dirt around the bottom and see if you can uncover a tag, which may or may not be still attached to the plant, and/or grown into the bottom stems -- I've found them both ways, even as much as twenty years after the plant was planted. (People ask me to ID things all the time, and you'd be amazed how often we can root around in the bottom of the plant and find the silly label still in the general vicinity -- the little round metal disk that used to come on nearly every rose which was how the breeders kept track of their licensing fees, when that system still worked.)

The striped one appears to be Scentimental

Thanks for your response! I think you're right about the striped one being Scentimental.

I may have to do some digging in the dirt tomorrow to figure out what the red one is!
