TPMS on custom wheel
The custom wheel valve stem is circled in the following pic:

Is the OEM TPMS/valve shaped like to custom wheel one? Just a simple replacement?

For cosmetic reasons, many of the exotic aftermarket wheels mount the valve stem in some manner like you're talking about.
Because in some aftermarket wheels you can't mount the tire pressure sensor in the manner they're mounted in an OE wheel, it may require that they are mounted with straps/bands (large hose clamp) in the drop center of the wheel, or there are some brackets available to mount them insdie the wheel.
Sometimes this presents problems programming the tire pressure sensors into the TPMS computer memory in the car. The TPMS tool required to trigger the sensor (force it to transmit its data during the programming procedure) has limited range - its antenna must be within a couple inches of the sensor in order to trigger it.
If you do mount the sensors deep inside the wheels with bands or brackets, make sure you mark EXACTLY where they are in the wheel so you can get the antenna of the TPMS tool as close as possible to the sensors when programming them.

Below is a bracket. It includes a bent valve stem that sticks out of the wheel, and there's a mounting loop that allows you to bolt the sensor completely inside the wheel:

And below is a link to a banding system:
