Function:

Blue hose adapter 1/4" M to 7/16" SAE F, with valve core and swivel. Used for R12 low side port.

Red hose adapter 1/4" M to 3/8" SAE F, with valve core but no swivel. Used for R12 hi side port. (On this one the seal inside mine looks a little deformed.)

90 deg adapter 1/4" M to 7/16" SAE F. With valve depressor. R12 low.

90 deg adapter 1/4" M to 3/8" SAE F. With valve depressor. R12 hi. Some older vehicles had the same fittings on both low & hi sides, so it's useful to have two adapters.

90 deg adapter 1/4" M to 1/4" F. With valve depressor. The 90 deg ones are good for accessing ports where there is not a lot of clearance.

Straight adapter 1/4" M to 1/8" NPT M. With valve core. Could possibly be used on a gauge manifold.

Straight adapter 1/4" M to metric 9x1mm M. With valve core.

Big adapter. 1/4 Male fitting is fine, female fitting is too small for 1/2" ACME, seems loose on 1/4" flare. Has valve depressor.
