Here are the verses I gave her. She expanded those verses and gave them context.
[Quran 9:29]
Fight those who do not believe in God, nor in the Last Day, nor forbid what God and His Messenger have forbidden, nor abide by the religion of truth—from among those who received the Scripture—until they pay the due tax, willingly or unwillingly.
This verse is a command to fight in battle the Byzantine Romans after the assassination of one of the Prophet’s ambassadors.

[Quran 2:190-191]
And fight in the cause of God those who fight you, but do not commit aggression; God does not love the aggressors. And kill them wherever you overtake them, and expel them from where they had expelled you. Oppression is more serious than murder. But do not fight them at the Sacred Mosque, unless they fight you there. If they fight you, then kill them. Such is the retribution of the disbelievers. But if they cease, then God is Forgiving and Merciful.
This verse commands Muslims to fight in battle pagans of Mecca after they expelled Muslims from their homes.

[Quran 47:4]
When you encounter those who disbelieve, strike at their necks. Then, when you have routed them, bind them firmly. Then, either release them by grace, or by ransom, until war lays down its burdens. Had God willed, He could have defeated them Himself, but He thus tests some of you by means of others. As for those who are killed in the way of God, He will not let their deeds go to waste.
This verse was revealed in context of war.

[Quran 8:11-13]
He made drowsiness overcome you, as a security from Him. And He sent down upon you water from the sky, to cleanse you with it, and to rid you of Satan’s pollution, and to fortify your hearts, and to strengthen your foothold. Your Lord inspired the angels: “I am with you, so support those who believe. I will cast terror into the hearts of those who disbelieve. So strike above the necks, and strike off every fingertip of theirs.” That is because they opposed God and His Messenger. Whoever opposes God and His Messenger—God is severe in retribution.
This verse is in context of Battle of Badr.

The website you copied this verse from provided poor and misleading translation, here's the correct one:
[Quran 9:123]
O you who believe! Fight those of the disbelievers who attack you, and let them find severity in you, and know that God is with the righteous.

[Quran 48:29]
Muhammad is the Messenger of God. Those with him are stern against the disbelievers, yet compassionate amongst themselves. You see them kneeling, prostrating, seeking blessings from God and approval. Their marks are on their faces from the effects of prostration. Such is their description in the Torah, and their description in the Gospel: like a plant that sprouts, becomes strong, grows thick, and rests on its stem, impressing the farmers. Through them He enrages the disbelievers. God has promised those among them who believe and do good deeds forgiveness and a great reward.
This verse was revealed when the Prophet Muhammad (peace be upon him) was returning to Madinah when he concluded the Truce of Hudaiybiyah. It refers to the Muslims who did not in any way cowe away or abandoned their faith in Islam, no matter how much the Quraysh were hostile, and persecuted the Muslims.

[Quran 4:88-90]
What is the matter with you, divided into two factions regarding the hypocrites, when God Himself has overwhelmed them on account of what they did? Do you want to guide those whom God has led astray? Whomever God leads astray—you will never find for him a way. They would love to see you disbelieve, just as they disbelieve, so you would become equal. So do not befriend any of them, unless they emigrate in the way of God. If they turn away, seize them and execute them wherever you may find them; and do not take from among them allies or supporters. Except those who join people with whom you have a treaty, or those who come to you reluctant to fight you or fight their own people. Had God willed, He would have given them power over you, and they would have fought you. If they withdraw from you, and do not fight you, and offer you peace, then God assigns no excuse for you against them.
This verse clearly talks about the hypocrites who lived at the time of prophet Muhammad (peace be upon him).
The point is, regardless of context, those verses are there. They exist. Pretending that they don't is naive at best. Furthermore, it's these verses (and many more like them) that have fuelled and justified the actions of Islamists for the last 1400 years.
