Take a look at

https://my.st.com/content/my_st_com/en/products/microcontrollers/stm32-32-bit-arm-cortex-mcus/stm32-high-performance-mcus/stm32f4-series.html?querycriteria=productId=SS1577

.  for the  first question.

For the second , Any peripheral can be used same time with any other peripheral;

Exceptions

pin availability for exclusive or shared use from each peripheral

Errata sheet limitations.

By definition from ST writen clear in ref manual (no company wants this kind of limitation for their products)

i got this information in datasheet of one of STM32F7 board

The current version supports only one SD/SDMMC/MMC4.2 card at any one time and a stack of MMC4.1 or previous.

what does it means????As we have separate pins for both interfaces ,i can communicate using 2 sdio pins with different devices at same time?????
