What will happen if we pray every day

What if you don't pray five times a day?

Prayer is the second pillar of Islam and is probably mentioned over 100 times in the Koran. Failure to pray during the prescribed times is a sin: it is listed as Main Sin 4 in Main Sins by Imam Shamsu ed-Deen Dhahabi (pdf). See also If someone does not pray 5 times, is he / she a bug?

... why doesn't any of the Muslims I know do that?

They will have their own individual reasons; It is not appropriate to speculate. You may actually do your five prayers, but you just don't notice. When I have asked people in the past, they have replied, "I pray in my heart," "I am not that devout," and "We only have to pray three times a day". I pray five times a day.

Is there some kind of automatic release from the obligation to pray when you live in a non-Muslim country?

IslamWeb write:

Regarding immigration from a non-Muslim country to a Muslim country ... those who are unable to fulfill their religious obligations and commandments or who fear temptation (i.e. in difficulty due to the poor environment and the spread of disbelief) the place to where you live). These Muslims are obliged to migrate.

And if they break the rules, what are the consequences?Will Allah punish them in Hell?Will they only have 71 virgins in heaven instead of 72?(I don't mean disrespect when I say this)

Only Allah decides who goes to hell or not. This is what he says (translated into English):

But it followed Followers who neglected prayer and pursued desires;this is how they will encounter evil except those who repent, believe, and do righteousness ; for these will enter paradise and do nothing wrong at all. - Quran 19: 59-60

O you who believed Do not let your wealth and your children distract you from the memory of Allah.And who does that - then those are the losers. - Quran 63: 9

So woe to those who pray without regard to their prayer - Quran 107: 4-5

(It's possible the 72 virgins thing was just a fabricated thing: do Muslim martyrs really get 72 virgins in heaven?)

It is questioned on the Day of Resurrection:

It was reported from Abu Hurairah that the Prophet (ﷺ) said: " The first thing a person will be held accountable for on the day of resurrection is their salah. If it turns out to be complete, it will be recorded as complete, and if something is missing he will say, "Look and see if you can find voluntary prayers to complete what he made of his mandatory Neglected prayers. " Then the rest of his deeds are calculated in the same way. "- Sunan an-Nasa'i 466 [Class: sahih] (sunnah.com)

In short, what if you don't pray five times a day?

Aside from being compulsory, prayer has a number of benefits. see e.g. bakkah.net. There is a section entitled "The Benefits of Performing Prayer" listed in "Main Sins" above. An important one is

Narrated by Abu Huraira: I heard Allah's Messenger (ﷺ) say, "If there was a river at the door of any of you and he bathed in it five times a day, would you notice dirt on it?" They said, "There would be no trace of dirt left." The Prophet (ﷺ) added: "This is the example of the five prayers with which Allah extinguishes (annuls) evil deeds. "- Sahih al-Bukhari 528 (sunnah.com)
