In the first picture, the masts are straight, and the shrouds look just fine. Shrouds are there to prevent lateral movement and keep the masts together (also prevents upward movement). So your shrouds should be fine. I notice that you do NOT have the bowsprit rigged yet either. That must be done first in order to rig the forestays, otherwise your masts will pull forward.
In the second photo, the foremast is bent at the fighting top - and it looks like both the lower and topmast are bent, meaning you may have broken the lower foremast. All of the backstays are straight, meaning they are very tight, while the mainmast stays are slack while the forestays (from the bowsprit to the foremast) are tight. I would start with releasing all of the foremast backstays. Shrouds should be fine. Once you release all that tension on the foremast, check to see that the lower mast isn't broken. If it is, then you might be able to save it by drilling a hole in the top and inserting a brass rod (since the lower masts are all hollow). Hide it by gluing on a small piece of flat stock.
Once the mast is straight again, check your forestays (you may need to tighten these up now), and then add the backstays back with less tension. Hopefully this will work.
