According to the 2005 NEC Annex C, table C.1 you are allowed nine #12 THHN conductors in a 1/2" trade size EMT conduit. If your conduit run is any length at all, you would be wise to increase the conduit size to 3/4". as pulling 9 #12's for any length in 1/2" EMT is very difficult.

Yes. Actually they should be run in the same conduit. You don't ever want to run parallel separately.

For a 400 amp service, you would typically use a minimum of 3-inch rigid metal conduit (RMC) to accommodate the large conductors required for that amperage. It's essential to consult local electrical codes and regulations to ensure compliance with sizing requirements for your specific installation.

using half inch conduit for a 13 in 90, the bender takes up 5 inches so you subtract 5 inches from 13 inches and place the arrow at 8 inches.
For five runs of #12 AWG conductors, a minimum of 1 inch PVC conduit would be required to meet the fill ratio requirements, providing adequate space for the conductors while allowing for future additions or modifications.
