I don't know of a specific area to find houseplant pictures, but usually a google search of "common house plants" will bring you to many websites that will state many of the most common houseplants with pictures. Alternatively, you can do the same to google image search, and it will give you pictures of the most common houseplants. You can click on the picture and find out what it is from there.

This looks like Houttuynia (chameleon plant) which has a reputation for being aggressive. It is a long-term effort to eradicate it. Basic options are hand removal and herbicide. It is somewhat herbicide resistant so more than one "dose" may be needed. Glyphosate is the least toxic herbicide for the environment. More info here: https://ask.extension.org/questions/183060

The problem with all squash, melons and cucumbers is that they freely hybridize. That means if you did not plant them, they may be a cross between two plants from last year. Did you plant any squash, melons or cucumbers then?

If you threw seeds from squash you purchased into your compost pile, you may have that variety with no hybridizing.

The best way to tell what you have it to cut them open and see what's inside, what it smells like, what it tastes like...

This looks like sweet autumn clematis, Clematis terniflora. It has sweet smelling flowers but grows aggressively. It is labeled invasive in some areas. Here is a good article on the vine. If you decide to remove it, dig out as much of the root system as possible, watch for re-sprouting and new plants popping up from seeds. http://www.missouribotanicalgarden.org/PlantFinder/PlantFinderDetails.aspx?kempercode=a300

There are a few apps that I have heard of, but after investigating myself on a few of them-the reviews are not so great! Feel free to do a search for such apps and see what you think! We don't recommend any such apps.!

It's hard to get a positive ID of the tree without flowers or seeds, but from the leaves it appears to be a poplar, like aspen or cottonwood.

Leaf margins turning brown, leaves yellowing and dropping, can surely be related to the extremely dry and windy conditions you describe = water deficit (drought stress). Give the tree an immediate deep watering and then once a week through the summer hot dry period.
Insect pest activity can be secondary to the drought stress. From the photo the feeding doesn't appear severe.
