Q:

If you are late for Zhuhr (but before Asr) do you pray the 4 rakats before or after zhuhr and if its after that means you prayer 6 rakats yes?

A:

In the Name of Allah, the All-Merciful, the Mercy-Giving.

All praise is due to Allah. Peace and blessings be upon His Prophet Muhammad.

If there is no enough time before AsrPrayer to perform these four supererogatory rak`ahs, then one has to perform the obligatory Zhuhr Prayer first before time is over. Then one may make up missed regular, supererogatory prayers (rawatib), according to the most preponderant opinion among Muslim jurists.

Aishah (Mother of the Believers) reports that if the Messenger of Allah (peace and blessings be upon him) missed the [supererogatory] four rak`ahs before Zhuhr Prayer, he would perform them after that (Al-Tirmidhi).

Yes, in this case, adding these four rak`ahs to the post-Zhuhr regular, supererogatory two rak`ahs makes the total six rak`ahs.   

Allah knows best.
