The sunfish both look like Bluegills to me. The weeds look like Chara, but to be sure, can you take a single strand that's about 10" long or so, put it on a white paper plate or white background and take a close-up picture of it? Does it smell musky if crushed in your hands?
The trout might be fattening up on natural forage. In my pond it took them a few days to get used to the food being tossed out. Same place, same time will speed things up. I'd toss out a handful or 2 each time. Cut back if the food isn't gone in 15 minutes.
