what are these hoses?

[theredmeadow]

I just started a 70 C10 longbed restoration. What are these hose part names? They are leaking because as you can see the previous owner went from rubber hoses to metal back to rubber underneath. I would like to replace them but I have no idea the part names. Can you guys please help? Also, the 2nd picture has the cut bigger hose in the middle of the picture, is it supposed to be cut and what is it(part name)? Thanks guys!
