Oh, thank you thank you! That's it! There is no Maranta in it. I think that was just a weird angle of a browning leaf. lol. I DID recently just get a few discount prayer plants, though they are not in this pic. Yes! That is a Persian Shield! I got it as a discounted, very sad looking plant a few weeks ago. The new leaves look much healthier, and more purple. The other plants in the background of that pic are an aloe plant that I'm trying to nurse back to health after soggy soil, and a jade plant. The plant in the foreground is, I think, an echeveria. I was sort of a ditz and was looking for a plastic plant tag for the name. On the barcode on the side of the pot, it said "echeveria species." So yay! It looks like I have a good shot at rejuvenating it, or at least starting new plants from the leaves.

Willow with pine cone willow gall.

Might possibly be orange rust. Contact your local office of your state universities USDA Cooperative Exgtension Service and take a sample, sealed in a plastic bag, in for ID and what you can do about it, which probably means removing the plants.

The big leggy fellows are crane flies. Not a problem to anyone or any plant. They're just hanging out. As for the 3rd picture -- too little detail to be certain of the ID. Doesn't appear to be a broccoli raab damager.
