1.TThis sentence of course literally says, 'It's equal to the one of him', contextually 'It's the same as his.' This construction is drilled in Unit 13.
Note that with days of the week no word equivalent to English 'on' occurs.
3.This is given as a unit expression because of the occurence of the itempor in the meaning 'during' or 'in', which it regularly has only with time-words like 'morning', 'afternoon', and so on.
4.Nothe that this answer is to the question ¿Que tengo que hacer?, which has the form,the infinitive, of hacer. Consequently, the answer merely replaces hacer with a series of verbs all in the same form, much as we would do in English in such a sequence as 'What do I have to do?' 'You have to eat, to wash up', etc. But notice: the 'have to' must be present in the English answer, though it does need to be present in the Spanish answer.
5.The item don is used only before the given name, the 'first' name, not the surname. It is translatable by 'mister' except that 'mister' is ised only before surname (though in the South one may hear servants talk about 'Mister Bill' or the like). It is rather formal. Doña is the feminine equivalent of don.
See (5) above for explanation of why Mr. Molina is used to translate don Jose.
Bastante occurs more often in this sense of 'rather' or 'quite' than it does in the more literal sense 'enough'.
