They might be planaria or some other type of pond critter. Small
invertebrates of all kinds may exist in your tank, but only become
noticeable when they have a population boom. Most of these critters
are detritivores, and they can multiply rapidly if their food supply
increases. Be sure you aren't overfeeding. You may want to vacuum
your gravel a bit.

Probably some kind of fungus subsisting on materials in the wood.
Loricariid catfish (plecos and relatives) often regard this stuff
as a delicacy and will eat it as fast as it grows. Even without
the plecos, it will eventually (months) go away on its own.

So-called brown algae (it's actually diatoms - real brown algae is like
kelp) is common in newly setup tanks, and later usually fades out. The
stuff you've got now is probably what is called green spot algae. The
best cure is a single edge razor blade applied every so often.
I hope this helps!
