Please help with these trees

[Viks808]

we just bought a farm and I’m new to trees. I have no idea what these trees are. We got this place and everything was overgrown and not taken care of.
The first two are the same tree.
The 3rd and 5th are the same tree.
And the last two are the same tree.

Where are you located?

Hawaii, but up where it’s coldwe. Waimea/Kohala area. Tropical plants don’t grow at our elevation.

Trees from that part of the world are out of my wheelhouse. Sorry. Hopefully someone on here will be able to jump in and help.
