So pretty new to fishing. Been about a year or so. Decided to buy some Shakey heads and see what it’s about but for some reason I can only find 4/o size. Is this the only size they come in? I bought some big bite squirrel tail worms and am curious if they will work fine on a 4/0 Shakey Head...thanks for any advice ?

If you look around there are lots of shakey heads. Some have different hook size, head shapes etc.  The plastics guys use them vary a lot too. Worms, craws, and creature baits have all been used with success.

3/0, 4/0, 5/0, 6/0, even 7/0.

Do you have the 4.5" or 6" Big Bite Squirrel? If you have the 6" I would say the 4/0 would work well. The 4.5" worm would be a bit small for me to use a 4/0, I would go down a notch and stick with a 3/0 for the 4.5" worm.
