2000 Jeep XJ. No idea what these parts are called. Thanks for the help.

The first part is the piece of tubing with a hole in it.

The second one is the three tubes running off the intake manifold.

 

Vacuum hoses. You can buy new sets. Head over to rock auto. Easy diy replacement.

 

The first pic is the CCV vent line and the hood release cable has rubbed a hole in it. It should idle smoother if you fixed that. You can cut it and insert a piece of rubber hose to join the 2 ends. The other 3 are vacuum feeds for the evap system purge pump and solenoid, and from the looks of the one on the right with the check valve it it, that's the vacuum feed for the heater control, cruise control, and vacuum reservoir. You don't need the plastic line for any of them, but if you use rubber hose, be sure to support it.
