Does anyone know the difference between meaning Capitals letter or Block letters?
Are both accepted, aren´t they?
Do the mean the same?
Is there any difference between them?
The common term is 'capital letters'.
In my experience, 'block letters' often refers to capital letters that are printed by hand, although you could also just call these 'capital letters'. Often, 'block letters' are large, eg when written on a blackboard.
