Sorry for the delay in answering, and that I can't really answer all of your questions, but here we go:

It really depends where in Spain you where during the Revolution; that is, whether you were in an agricultural community or in the city. And even then, it varied quite a bit.

For the majority of industrial workers in Barcelona, the stronghold of the revolution, at the beginning, life improved a fair bit. New wage levels and working conditions were introduced and enforced by the unions that controlled the city. Consolidated industries increased the productivity of the economy for a while, and the tram network of Barcelona was famously consolidated out of several companies and made a lot more efficient. Women were no longer quite as limited as they were beforehand, now being able to work in some cases alongside men in factories and being allowed a lot more freedom on the streets (somewhat foreshadowing the later women's liberation movements with the Mujeres Libres movement). However, there were still cultural aspects remaining that still discriminated against women and many still held the attitude that women belonged at home.

In the countryside, it depended on whether the community had an existing enthusiasm for the revolution. In areas where they did, the land was quickly collectivised and the collectives successfully kept up and, in some cases, increased agricultural production. Communities where this was a lot more reluctant and forced, however, fared a lot worse and in many cases returned to subsistence level production.

As the war went on, the influx of refugees and the inconsistencies in the countryside with agricultural production and raiding of farms, as well as the ever growing need of food supplies, living quality expectedly went down a fair bit. In 1937, halfway through the war, the CNT and UGT decided to reimplement the much loathed piecework, which had been a main fighting point long before the war, in order to bolster production. Food became scarce and the Republic's overissued and barely-recognised currency rapidly inflated. The early wage increases started to mean very little for many. But, by that time, the main part of the revolution was already over and suppressed by the government, and much of these later things can be attributed to wartime pressures. The Revolution really didn't last long enough for us to make a brilliant assessment of what life could have been like, and the presence of the war greatly influenced many aspects of it.

Post-war Spain was an odd era for many. Many were forced underground or out of the country, and millions of workers who had previously supported the Republic were forced into a silence by the ever present Francoist state apparatus. For those that joined the right groups and said the right things at the right times, life wasn't all too bad, but for others it could get a lot worse, especially political dissidents still in the country.
