I started reading up on them, and it turns out there's so much I don't know!
First, I know I need to move them from their tiny little pots, but will they survive outside over winter (we're in zone 3), or should I plant them in larger pots and move them inside? There seems to be more than one plant per pot, so I was thinking of bringing in half of them and planting the other half in the garden. That way at least half of them might survive... hopefully?
Second, two of them have yellow leaves, and one has white spots that look like droplets of bleach all over the leaves. Does anyone have any suggestions about what's causing this, and what I can do about it?
And finally, can anyone tell me what type of roses I've got? I know that different mini roses need different care, but I'm not sure how to tell them apart. Here are a couple of pictures:
My red one! It managed to hang on to a couple of it's flowers but, as you can see, most died. It also has the fewest yellow leaves.

This one had white flowers with a soft, pale green tint to them. But they all dried up and died, along with a bunch of leaves. The leaves are starting to grow back, but not the flowers.


This is my favorite one! It lost all its flowers, but one grew back. The leaves have some sort of weird mottling though.


Thanks so much if you made it through my whole rambling post. I really appreciate any suggestions or information you could share!
