When putting a hose bibb in, where the pipe will be going through brick, does copper pipe need a sleeve, or can it be run directly through the brick?

Ron

A sleeve is always a good idea to prevent the copper from being in contact with the bricks or cement, it is the preferred method for this type of installation. Also, installing a threaded fitting on the exterior to ease hose bibb replacement down the road and an isolation valve on the inside can't hurt. Freezing shouldn't be a factor in AL, so it probably doesn't need to be a frost-free type hose bibb or set up for draining purposes. A vacuum breaker may be required in your area for the hose bibb.

What do you usually use for a sleeve? pvc or some type of steel/iron pipe?

A local guy suggested on the water supply line coming into the house to put the copper into a cast iron (I think) sleeve, that would bridge the area between the basement wall and the stable ground that wasn't disturbed while digging the basement. That's why I ask about materials.

If I was going to sleeve the water supply tube, I think I would use abs plastic, or equal. It will insulate the hydrant from the house, and cushion any movement in the pipe to the h.b..
Not that there should be any movement anyway. But people do twist pretty hard, on the valve handle, so there will be chafing of the pipe if unprotected.
Good Job,

I will either use a copper sleeve or wrap the pipe with tape to keep it from contacting the masonry surfaces.

steel or iron will rust and look awful after a few years. a short piece of 3/4" copper makes a good sleeve for 1/2" copper.

Stick with the suggestions to use either a larger diameter plastic or copper pipe. Don't use a dissimilar metal like iron since this will develope galvanic corrosion and will lead to a "leaky" copper pipe through brick.

Then pack the sleeve with insulation and silicone the ends to make it weather proof.

Not really because there should not be any water to act as an electrolyte.
