Wood ID help

Was walking the property over the weekend and found where the power company contractors had dropped some trees. We have plenty of oak, maples, hickories, cherry, pine, etc. on the property so we have good options, but wasn't quite sure what these trees were and need help with them. Three different pictures of three different trees. They just need sliced up and split now. Any ideas? Thanks!

Thanks for all the replies! Figure most of this is worth cutting up since its already down and easy to get to. As for the snow on the ground PA Woodsman, we've had a mostly snowless winter down here, which is actually unusual for our location, lots of rain in the 30's and low 40's is the story this winter. We certainly have all the varieties everyone mentioned, that's what makes it difficult to determine and I know the pictures aren't the best. I'll put a couple more pictures below, maybe they will help or maybe not? We have most hardwoods, just don't have any native birch or native sugar maple, although scored a great sugar maple from someone's yard last week! Very fortunate.

Definitely thinking image5 (the one the right) is some type of oak, its the other pictures and other trees I am "stumped" on. I've had folks say black gum, and then all the other possibilities, but its like English BoB said, its all tight grained good BTU hardwood, so why not cut it and split it?

TreePointer, I tried the stiff test yesterday and I def feel like 1 of the 3 types I have questioned is some type of oak. We have lots of red and white and others too. The smaller, alligator scaled specimens are still confusing to me (images 2 & 4 above). I can believe maple as there are quite a few of them around. The area is just above a small creek too and not a high and dry spot. My final question is what is image 1 above. I'm going to add more pictures I got yesterday of that tree. Ignore the small section of poplar in the picture showing the trunk lying on the ground. I'm providing a picture of the stump, the trunk structure and a chunk of the wood that has been sawed off. I'll say, the chunk is already beginning to dry fairly quickly and I'm guessing the tree was dropped within the past 2-3 weeks? Thanks again for everyone's time and suggestions! I've come to love this site and appreciate the wealth of knowledge and information.

Applesister, thank you for those suggestions. I should certainly have thought of picking out the leaf litter and seeing what I had. I have done that elsewhere before and to determine what type of nut/fruit litter there was as well. The property is family land, so not mine personally, but I can roam and harvest trees/wood as I please, so very fortunate in that respect. It was a very tangly mess before power company contractors went through and thinned some things. This spot is immediately adjacent to a high tension powerline right-of-way. They dropped the trees and even cut them up some, so easy pickings. Thanks again to all!
