I would like to ask, however,... if it is not normal for TUBE tires to drop 2 lbs a week, for what kinds of tires would that slow leak be normal?

Tires are rubber. Rubber is pourus. (porous?) *spellcheck* // They all eventually leak some, especially with temp change. Usually colder weather causes them to read less pressure. I assume this also has to do with heat expands//cold contracts. If you check them regularly, you should notice a pattern, over time.
That said, having worked in the tire business for 23 years, it was a common thing to be airing up tires as soon as the cold weather moved in. But even in summer, almost every car on the rack had low tire pressure. That's one reason why we had to check every tire on every car.
I would air them up and then check them every day for the next week. If it goes back down in that time, then you probably have a leak.

How does WD40 fix it??

Deflate the tire, take the core out of the valve, and stick the WD40 red straw in the valve stem and squirt. The idea is to dislodge any small chunks sitting there that might cause a leak. Clean off the core as well before you insert it back into the stem. Use a metal valve cap with a rubber seal inside as insurance.

Some guys don't like to squirt oily stuff into the valve stem (thereby squirting oily stuff into the tube), so they just use compressed air.

Any tire place has them, or auto parts places. For mere pennies !! And if it still leaks out the valve then, you need a new tube.
