From the pool lane in California can you cross over when you have a white line and next to it is two yellow lines to get to the outside lane?

Can't answer for California, but in New York the answer is no - you may not cross a double solid line to enter or exit a car pool (HOV) lane. I suspect the answer is the same for California.
Entering and exiting the carpool lane on the freeway is regulated by the type of line on the right hand side of the lane. The driver can enter or exit the lane only when the lane is not bordered by a white solid line.
Deceleration lane AKA, Ramp
A weave lane is the part of the highway or freeway where both an entrance and exit exist. It is called this because cars will be weaving in and out of lanes to either enter or exit.
Do Not Cross/ Stay in your lane Do Not cross double lanes to pass another vehicle
The lane on the highway designated as the exit only lane is typically the rightmost lane.
6 As you enter the deceleration lane or the exit ramp, slow down and check your surroundings for other vehicles before merging safely into the flow of traffic. Make sure to use your turn signal to indicate your intentions to other drivers.
deceleration lane
Be sure to reduce your speed gradually, signaling your intent to exit. Check your surroundings for other vehicles and safely merge into the exit ramp or de-acceleration lane at a slower speed than the main roadway. Maintain a safe following distance from other vehicles as you prepare to exit or merge.
SAFELY merge into and through the slower lanes of traffic. If you cannot do so before your exit is reached, continue on the next exit by driving in Lane 4 - exit there and then return one exit to your original destination.
The number one lane
The purpose of an exit only lane on a highway is to provide a designated lane for vehicles to safely exit the highway without disrupting the flow of traffic in the other lanes.
