I know we cant pray any pray after Asr until Magrib or any pray after Fajr until sunrise

but apart fromt hat can we do our kaza salahs for the ones we missed in the previous years anytime during the day apart from the times mention above -

some people say you cant pray fajr and zohar and asr kaza after magrib or ishas and vice versa -but some people say you can - i sometimes do all my kaza salahs in the morning , sometimes after maghrib or after zohar or isha -

is this right or should i be doing certain kaza salahs at certain times
