is it possible to run another 200 amp sub panel from the original 200 amp panel
to power a storage building.

Most of the 200 amp panels only accept as a max size breaker of 175 amp.
As long as your calculated load does not exceed any rating of conductor or equipment, yes.

And the meter base is approved for more than one set of load conductors (if that's the plan.)
Your original post stated "sub-panel". Although not NEC defined, a sub panel is normally though of as a panel fed from another, the second being protested by the first.
In a later post you mentioned coming from the meter pan to both panels. Normally that is not considered a "sub panel".
As mentioned, in the meter pan install, there are several factors.
a. Will the lugs rated to accept two wires ?
b. Is the calculated load within the rating of the conductors supplying the meter.
c. Do the conductors to the shop ever enter the residence ?
d. Will POCO accept (in some of the local jurisdictions, POCO prohibits such installs)

The 200 amp panels I have seen will only take a 125 amp breaker on the bus bar.

i can either use a sub-panel off the first panel or run 2 200 amp panels out of the meter Socket with some double lugs.
i would like to know if i put double lugs on the meter socket can i run
2 200 amp panels off of it.

as stated....
you can.. IF
The calculated load does not exceed the ampacity of the conductors feedeing the meter socket or the rating of the socket itself.
(unless someone planned ahead it would be rare that your original socket met that criteria)
If the panels are serving (or enter) the same structure, you need to meet 230.72

it is a detached Storage that will be remodeled to a living space/shop
what would be the best way to supply a 200 amp panel to it.
it is about 200' from the existing panel.

You could also use a W/P gutter and splice your conductors to feed the two panels.

Well, have you done a calculation for both buildings, the answer to your question is more involved than just feeding a second panel.

Part time-- you cannot get a 200 amp supply out to the other structure if you are feeding the house also. Why not install a 400 amp double lug meter base and feed one panel for the house and the second 200 amp panel for the detached structure.
You can pull a 200 amp feeder but that will not give you 200 amps.

The "best way" can only be determined by looking at a number of possibilities.
Will POCO serve it separately ? Not necessarily the most economical long range but perhaps the simplest.
Beyond that possibility, as Roger states, Step 1 is to calculate your load. including
projected load...both structures (You will need this to properly size your new line anyway as with 200ft, voltage drop may be an issue).
Most common arrangement I see if the existing panel won't supply, is to install a 400 (320) amp meter with adequately sized riser (lateral) and reconnect the existing service then run directly from the meter to the other structure.

Yes , snap- in panel to 125 amp but bolt- in panels to 175amp! With a 225 amp buss .

I am thinking resi here so snap in is what he will use.

320 or 400 amp meter socket will cost less than 200 amp with aux gutters splicing meterials and labor to put it all together, and will look better when finished.
