Since the 5 points of Calvinism come from the 4 heads of the canons of Dort, I can say yes.
1. I believe that all are totally depraved meaning that every single person in Adam is a sinner and has no desire to come to Christ. The Spiritual things are foolish to him and he does not seek after God. This does not mean that man is as evil as he can be, but that evil has affected his entire being. His nature is corrupt. He is dead in his trespasses and sins and thus cannot do anything for his salvation.
As all men have sinned in Adam, lie under the curse, and are deserving of eternal death, God would have done no injustice by leaving them all to perish, and delivering them over to condemnation on account of sin, according to the words of the apostle, "that every mouth may be stopped, and all the world may become guilty before God" (Rom. 3:19). And verse 23: "For all have sinned, and come short of the glory of God." And Romans 6:23: "For the wages of sin is death."

2. I believe that since man has no desire to come, God in his love has chosen to save some. This election isn't based on foreseen faith, good works or anything good in man, but rather that God chose to save "according to the good pleasure of his will." If election was based on foreseeing good in man, none would be saved. This election was done before the foundation of the world. (Eph 1:14)
3. The atonement of Christ is sufficient to expiate the sins of the whole world. It's efficiency is only to believers/elect. The atonement is meant for only believers. It was never intended to save those who die in unbelief.
4. Those whom God has chosen to be saved will be saved. (John 6:37) those whom God has chosen to be saved will be saved. They are not born saved but will be saved in time. The nonelect will resist God their entire lives. The elect may resist for a while(usually will) but will before they die come to Christ. God will convict their heart and change it from a heart of stone to a hear of flesh. (Ex 36:26)
5. All those that are saved will be kept by the power of God. As the cannons say, "Those thus saved God graciously preserves so they persevere until the end, even though they may be troubled by many infirmities as they seek to make their calling and election sure." John 6:37, John 10:28.
