I think that at one time the trellis extended all the way along that bed - the rose on the right and in the centre look like old climbing roses to me, and may rejuvenate well. I think the rose to the far left (the one with the yellow leaves) looks more like a rambler of some sort. All three will respond to being cut back as has been suggested. They will then shoot again from the bottom.
You can then tie them into the trellis (the one without trellis will need to have it replaced) training the stems out near to the horizontal - this will encourage the roses to develop side shoots which will bear more flowers.
Cut them back now to prevent windrock, but in the spring you can tidy them up properly, pruning to buds which will grow in the direction you want them to. Give them a mulching of well rotted farm yard manure now (not touching the stems) and when you prune them in the spring give them a feed with Fish Blood and Bone.
When they flower show us some photos and we'll have fun trying to identify them.
