All Muslims know that 5 times prayer is an obligation.
In other words ALL Muslims do NOT subscribe to a "non-literal" definition of "pray" and understand it as:
In other words ALL people with a Muslim identity are "literalists" in their undestanding of the Islamic prayer requirement.
Most Muslims don't do it 5 times a day.
First of all, on what do you base this statement? If true, it still leaves the possibility that most people with a "Muslim" identity pray 1-4 times a day. Again this does not involve a "non-literal" interpretation of the Qur'anic command to prayer.
If most have trouble with something as basic as that, I don't think you need to worry about a literalist majority.
By your own admission above, ALL Muslims subscribe to a LITERAL understanding of "prayer" and are therefore "literalists". If most don't do the full five it may be due to factors beyond their control like the lack of workplace provision of prayer time.
Most Muslims do eid prayer, never are there more people in mosques than in eid prayers, one of the few NON-OBLIGATORY prayers.
That appears to be
DEBATABLE to say the least. On what do you base your OPINION?
