I think the Double Knock Outs are correctly identified. Your other rose reminds me of Belinda's Dream, but I am not one of the better identifiers here. If you can get more pictures showing the whole plant, leaves, stems, thorns etc. it will make it easier to name. Also tell us whatever you know about it: fragrance, repeat bloom, health, all will help. There are thousands of pink roses so it may never get a certain i.d., but some folks on here are very good at this game.
And by the way: welcome to the rose forum!
