i have a mak90 that i have a choate stock, ultimak mount, and an american made red dot on do these count for 3 pieces of 922r compliance? what other items can i easily install to make full compliance?

I know the red dot isn't a part.

No.  The MAK-90 does not need compliance parts with a choate stock as that is a thumbhole.

The 922(r) parts compliance has been covered repeatedly.

On an AK the parts most likely used are

US parts usually used for compliance:
pistol grip
front handguards (count as one 1)
buttstock
fire control group / trigger, hammer, sear(disconnector) (3)
piston
muzzle attachment
mag baseplate
mag follower
mag body
receiver

stamped takes 5 or 6 depending on muzzle attachment
milled takes 4 without 5 with muzzle attachment
