OK, I googled this hammerhead worm. Here's what it said. I copied it from the website I went to. This "worm" is usually only seen during very high humidity situations, such as a lot of rain. They are usually found in cool, dark, moist areas. They eat earth worms, slugs, snails, insect larvae, and are even cannibalistic. They usually move and feed at night. They can survive desiccation only if water loss does not exceed 45 percent of their body weight. They have been found commonly in American greenhouses since 1901. Their mouth, which also serves as an anus, is present near mid-body on the ventral surface. Colors of Florida species range from greenish-grey to brown with dark narrow stripes on the dorsal side. Sometimes they are yellow or blue in other areas of the country. I just had to post this because I could not get over the fact that the mouth doubles as an anus. OK this means that he pukes out his poop!!! That is just gross!!!!

I had to google that one. There's a fungi worthy of exhibit space at the Whitney.

Appears to be a female Dobsonfly. Though the males have the HUGE mandibles, it is the female that can inflict a painful bite. I'd advise against handling, though I wouldn't be concerned about having them nearby. There must be a fresh water source fairly near (pond, lake, stream) as the larvae of these cool critters are aquatic (helgrammites). They eat anything they can grab in the water. It is not really known of the adults (which you have) feed on anything during their short life span.

A pupal stage of an insect, not sure which, from one picture; you can hold it in a terrarium until it emerges for a good ID
