Need help pinpointing where this stuff goes

[Nassol562]

I just recently got into being a mechaninc not too long ago and this ended up being my second car and i had to replace a head gasket. its been quite an experience for me and learned alot of this. and dealt with pain in the ass problems. One thing i forgot to do is take pictures of the car before i took it apart and now i am down to a few brackets that idk where they go and a bracket that dosent wanna bolt down. I have the manual and it dosent show me where it goes.

the first picture is the bracket i have no idea where it goes at. the second seems like its and air hose thingy idk i just dont know where it will go at i have the manual and i cant find it on there. im sorry my terminology is bad. and the 3rd is i cant install my pulley properly on the red bracket.
