I am learning. So, I delay all prayers and perform them at home all together. How should I perform them?

Praise be to Allah, the Lord of the World; and may His blessings and peace be upon our Prophet Muhammad and upon all his Family and Companions.

Know that it is not permissible to delay prayer from its fixed time unless there is a legal reason such as combining two prayers on a journey, or while it is raining.
Only in cases mentioned above can one combine al-Zuhr with al-'Asr and al-Maghrib with al-'Isha.
Know that if acquiring knowledge constitutes an obstacle that prevents you from performing or delaying prayer, then you have to give up such learning, since there will not be good in knowledge that diverts one from Allah's worship.
But, if a Muslim misses the prayers due to a legal reason such as deep sleep, then he has to make them up in their normal order, i.e. Fajr, Zuhr, etc.
Allah knows best.
