I will try to answer your specific questions as I understand them.
More specifically, are each of the Specialties a separate class, or does earning a Specialty mean you've done the required dives in that category?
Yes, each specialty is a separate class / course. But, you can get credit for prior experience under certain conditions (see subsequent comments, below). And, keep in mind that each
certification is not necessarily a
specialty. AOW is a
certification, not a
specialty in itself. Master Scuba Diver is a
certification, not a
specialty in itself.

Does that mean I've done two dives from a boat? Or do I do two new dives from a boat with an instructor, even if I've already done several dives from a boat without an instructor?
In order of your questions, NO (it does not mean that you have simply done two dives from a boat) and YES. You do not get credit for simply diving from a boat, diving deep, diving at night, etc. You get credit when you conduct the dive as part of a structured training experience, in which you meet the specific performance requirements of the dive(s), as outlined in the PADI manuals. For example, the specific performance requirements for the Boat Adventure Dive include: 1. Identify the following areas of the specific boat being used for the dive: bow, stern, starboard, port, entry area, exit area and area to stow dive equipment; 2. Locate important emergency/safety equipment aboard the boat (such as: first aid kit, oxygen, AED unit, life preservers, dive flag, radio and fire extinguisher); 3. Enter the water based on the type of dive boat being used. 4. Make a safety stop at 5 metres/15 feet for at least three minutes; 5. Exit the water based on the type of dive boat being used.

A second, but related questions; can I double dip? An example is I did a AWARE-Fish ID dive as part of my AOW cert. Do I do it again to complete the required 2 dives to earn the AWARE-Fish ID specialty? Or are those two additional new dives and training?
An Adventure Dive done as part of Advanced Open Water can count as Dive 1 of the specialty in question. For example, you complete 5 Adventure Dives as part of AOW - let's say Peak Performance Buoyancy, Underwater Navigation, Night, Deep, and Wreck. You have now completed Dive 1 of each of those specialties. To complete the Peak Performance Buoyancy specialty - as one example - you need to do Dive 2 of the specialty; to complete Night Diver specialty, you need to complete Dive 2 and Dive 3 of that specialty, etc. I am not sure I would say that would be a 'double dip'. At an even more basic level, you can earn a PADI 'Scuba Diver' certification if you complete a) all Confined Water training, and b) academics, and c) Open Water Dives One and Two, of the Open Water Diver curriculum. The 'Scuba Diver' certification has certain limitations on independent diving (diving without a dive professional). If you then complete Open Water Dives Three and Four, you can earn Open Water Diver certification - you do not have to repeat what you have already done. But, yes, the Confined Water training counts for 'Scuba Diver' and 'Open Water Diver'
Chuck J. Rylant:
Or what if I wanted to knock out several at one time. For example, what if I did two deep dives from a boat? Do I earn the "Boat Diver" and "Deep Diver" specialties with just two dives?
NO. You cannot get credit toward more than one
specialty for an individual dive. That may seem a little odd, since you are earning the AOW certification by doing 5 Adventures dives, each of which counts toward a specialty certification. But, AOW is not a 'Specialty' certification, per se. Just as with 'Adventure Diver', and to some extent, 'Master Scuba Diver', AOW recognizes that you have completed a certain number of Adventure Dives. If you complete 3 Adventure dives, you can receive recognition, through the Adventure Diver certification. If you complete 5 Adventure Dives (as long as those 5 include Deep and Underwater Navigation), you can receive recognition, through the Advanced Open Water Diver certification. If you complete 5 specialty certifications, and the Rescue Diver certification, you can receive recognition, through the Master Scuba Diver certification.
Chuck J. Rylant:
I realize there is little gained just in earning the Master Diver card or Specialty cards, but there is benefit in checking off boxes if only to provide a little additional motivation to learn new skills and get more experience.
Yes - the cards themselves are not the value - learning new skills and gaining more experience is the value. And, there may be, for individuals, a certain motivational value associated with recognition milestones (e.g. Master Scuba Diver) that you pass along the way to becoming a better, safer, more competent diver. Can you check the boxes, earn the cards, and successfully avoid learning new skills, or gaining more experience? Yes, just as you can go through an undergraduate curriculum, earn a Bachelor's degree, and come out of the experience as ignorant, uninformed, and uneducated as you were when you started. I went to school with several fraternity brothers who excelled in doing just that. But, in general, you can, and should, learn new skills and gain more experience through most / all of the specialty courses that you take.

Having said that, there may be a time when I'd like that little card or that silly piece of paper on the wall and it makes sense to do it as inexpensivly as possible without paying redundant fees if possible.
Nothing wrong with either sentiment. People can rail all they want about badge collection, but that 'silly piece of paper' (or plastic) often has some meaning - personal meaning, if nothing else - and that is fine. Why do you get a diploma (suitable for framing) when you graduate high school? An employer usually doesn't ask to see it - you put on a job application that you graduated from XXX High School in XXX year, and the employer may, or may not, verify the information. But, that 'silly piece of paper' has some meaning - perhaps for the student who somehow managed to make it through, more probably for the parents of the student who somehow managed to survive their child's high school years. Why do you get a diploma (sutiable for framing) when you graduate university? Why are the walls of physician's offices, and attorney's offices, to name just two professions, usually adorned with framed certificates, indicating that the named individual completed some degree, or training program, or experiential program. It is not required - public display of a license to practice a profession may be required in some situations, but display of training credentials generally isn't. Rather, the display is part of human nature, which generally includes a desire for some form of 'recognition'.
