Well, Katy's advice to get a schematic from the builders is the obvious way
to start but although I know nothing about this particular design of boat
here are some tentative suggestions within your message for your
consideration:-

I have bought an alberg 30 that is completely stripped out inside. I have
only had 24' and
under boats and there are a few more holes than I thought there should be
and was
hoping somebody could help me out. So here goes:

Port side forward, 2 larger holes which I know are the head intake and
discharge.

Sounds Ok if that is where the head is

Starboard side middle, one larger and another smaller that must be the
intake and discharge
for the sink. Is the larger one meant to be the discharge (about 1 1/2")

If that is where he sink is the larger one will be the discharge and the
smaller one is probably a sea water inlet for a small hand operated pump so
you can work with seawater at times on jobs which do not need the
expenditure of fresh water.

Starboard and port middle. Under the engine area, I expect the cooling
water intake and
discharge.

One will be the intake for sure but I can offer no suggestions on the other
as the discharge from the engine is almost always into the exhaust pipe

Starboard side way aft, a 1-2" above the waterline. I have no idea.

Possibly the engine exhaust outlet but might be a cockpit drain as there is
another one the other side at the same place, but then where is your exhaust
outlet?
Port side just opposite is another 1-2"
see above
and 2 smaller (1/2" or so) thru-hulls. Again, these
are above the waterline.

Don't know about these-they are too small for cockpit drains and anyway two
cockpit drains would not be the same side. One might be outlet for the bilge
pump (but seems a bit small for that) and the other possibly a drain from
the gas bottle container

Exactly center in the stern is a small 1/2 one with some copper piping
connected to it.

Maybe the vent from the fuel tank

Then there is the Speed log and Depth sounder.

Now I have 1 'hole' in the keel that goes through into the bilge. This
looks rough
and I think it was put there when the boat was stripped to drain the
bilge out. It's in
a spot that I don't think I can put a thru-hull in. So either it has to
be plugged or is it
meant to be there with some other type of fitting?

No suggestions for that one.

Any and all help is greatly appreciated.

Well, there you are. A few suggestions fo your consideration.
