Will All Muslims Go to Jannah?
Question

Will all the Muslims, including the hypocrites, those who did not pray and those who committed Shirk, enter Paradise after spending some time in Hell?
Praise be to Allah.Who will go to Jannah and who will go to Hell?
We should understand properly the general principle concerning this matter, the matter of entering Paradise and spending eternity in Hell. It is a simple matter that is explained in a brief Hadith that was narrated by Muslim (135) from Jaabir (may Allah be pleased with him) who said: A man came to the Prophet (blessings and peace of Allah be upon him) and said: O Messenger of Allah, what are the two deeds that make entering Paradise or Hell inevitable?
He (blessings and peace of Allah be upon him) said: “Whoever dies not associating anything with Allah will enter Paradise , and whoever dies associating anything with Allah will enter Hell.” 
An-Nawawi (may Allah have mercy on him) said: “With regard to the words, “What are the two deeds that make entering Paradise or Hell inevitable?” what is meant are the characteristics that make Paradise inevitable and the characteristics that make Hell inevitable.” 
This Hadith explains that what makes it inevitable that a person will enter Paradise is if he dies believing in Tawhid , and what makes it inevitable that a person will spend eternity in Hell is if he dies believing in Shirk. 
This is a definitive principle that is well-known and well established in the religion of Islam. There are Mutawatir texts which confirm and affirm it. Allah, may He be Exalted, says (interpretation of the meaning):
“Verily, Allah forgives not that partners should be set up with him in worship, but He forgives except that (anything else) to whom He pleases, and whoever sets up partners with Allah in worship, he has indeed invented a tremendous sin” [An-Nisa’ 4:48]
The Prophet (blessings and peace of Allah be upon him) explained, in the Hadith about intercession, the situation of the sinners in Hell, and he explained that no one will be brought out of Hell except those who died believing in Tawhid and uttered the Shahadah (Testimony of Faith), and had in their hearts something of faith: “There will be brought out of the Fire anyone who said, La ilaha ill-Allah (there is none worthy of worship but Allah) and had in his heart goodness equal to the weight of a grain of barley. Then there will be brought out of the Fire anyone who said La ilaha ill-Allah (there is none worthy of worship but Allah) and had in his heart goodness equal to the weight of a grain of wheat. Then there will be brought out of the Fire anyone who said La ilaha ill-Allah (there is none worthy of worship but Allah) and had in his heart goodness equal to the weight of a small ant.” (Narrated by Al-Bukhari, 6861 and Muslim, 285) 
Based on that, we can find out the situation of those mentioned in the question. 
Will those who died upon Shirk go to Jannah?
If a person fell into major Shirk, whether he was originally a Mushrik like the Jews, Christians, Buddhists and other types of disbelievers, or he was a Muslim then he apostatised from Islam by falling into major Shirk – as mentioned in the question – then his claim to belong to Islam or his having a Muslim name will be of no benefit to him, and neither will any good deeds that he did and so on, if he fell into major Shirk and died in that state without having repented. Allah, may He be Exalted, says (interpretation of the meaning):
“And indeed it has been revealed to you (O Muhammad), as it was to those (Allah’s Messengers) before you: ‘If you join others in worship with Allah, (then) surely (all) your deeds will be in vain, and you will certainly be among the losers.’ Nay! But worship Allah (Alone and none else), and be among the grateful.” [Az-Zumar 39:65-66]
Will those who do not pray go to Jannah?
The one who does not pray at all , either in his house or in the mosque, and does not attend Jumu`ah or prayers in congregation, has also rendered his good deeds invalid and has fallen into disbelief by not praying at all. The Messenger of Allah (blessings and peace of Allah be upon him) said: “The covenant that stands between us and them – i.e., the characteristic that separates the Muslims from the disbelievers – is the prayer. Whoever does not pray has disbelieved.” (Narrated by At-Tirmidhi, 2545 and An-Nasa’i, 459. Classed as authentic by Al-Albani)

Will the hypocrites go to Jannah?
With regard to the hypocrites, if what is meant is the people of major hypocrisy , namely those who make a show of being believers in this world when they are concealing disbelief in their hearts and hiding it from the people, they will be in a worse position than the disbelievers and the polytheists. Hence their fate will be in the lowest levels of Hell, as Allah, may He be Exalted, says (interpretation of the meaning):
“Verily, the hypocrites will be in the lowest depths (grade) of the Fire; no helper will you find for them.” [An-Nisa’ 4:145]
Will those who tell lies or break their promises go to Jannah?
those who fall into some acts of hypocrisy, such as lying or betraying a trust or breaking a promise ; or fall into some kind of minor shirk, such as showing off or swearing by something other than Allah; or who fall into some major or minor sin – such a person does not become a disbeliever just by doing that thing. It does not put him beyond the pale of Islam and he will not spend eternity in Hell because of it, if he dies believing in Tawhid . Rather his case is up to Allah: if He wills He will punish him for his sin, then admit him to Paradise because of his belief in Tawhid, or He will bestow His grace upon him from the outset and admit him into Paradise and forgive him for the sins that he committed. Al-Bukhari (6933) and Muslim (1659) narrated that Abu Dharr (may Allah be pleased with him) said: The Messenger of Allah (blessings and peace of Allah be upon him) said: “Jibril appeared to me at the side of the harrah and said: ‘Give your Ummah the glad tidings that whoever dies not associating anything with Allah will enter Paradise.’ I said: ‘O Jibril, even if he steals and even if commits Zina?’ He said: ‘Yes.’ I said: ‘Even if he steals and even if commits Zina?’ He said: ‘Yes.’ I said: ‘Even if he steals and even if he commits Zina?’ He said: ‘Yes, and even if he drinks alcohol.’” 
And Allah knows best.
