Wow, I too am impressed. I’m a seminarian, and I don’t have memorized some of those prayers you listed! (I admit, I do know most of them, though!)
Here are a few suggestions for you:
The various prayers from Fatima (you can find them all over the internet; here are some):
–My God, I believe, I adore, I trust, and I love Thee. I beg pardon for those who do not believe, do not adore, do not trust, and do not love Thee. (repeat three times)
–O Most Holy Trinity, Father, Son, and Holy Ghost, I adore Thee profoundly. I offer Thee the most Precious Body, Blood, Soul, and Divinity of Jesus Christ, present in Tabernacles throughout the world, in reparation for the outrages, sacrileges, and indifferences by which He is offended. By the infinite merits of the Sacred Heart of Jesus in union with the Immaculate Heart of Mary, I beg the conversion of poor sinners.
[NB: when the Angel taught the children this prayer, they were shown a beautiful monstrance with the Host; they bowed until their foreheads touched the ground, and repeated this prayer three times. Then, the Angel distributed Holy Communion to the three–for two, it was their first Eucharist (and what a first Eucharist to have!!). After, they bowed low again, and repeated this prayer three times.]
–O Most Holy Trinity, I adore Thee! My God, my God, I love Thee in the Most Blessed Sacrament!
–O my Jesus, forgive us our sins; save us from the fires of Hell. Lead all souls to heaven, especially those in most need of Thy mercy.
**The Magnificat and the Benedictus and the Nunc Dimitis **(that is, the Canticles of Mary, Zechariah, and Simeon, prayed at Evening, Morning, and Night prayer respectively)
Do you pray the
Divine Office? Also called the Liturgy of the Hours or “Christian Prayer”, it is the prayers of the Church. Let’s just say, the Divine Office is so important that all priests are obliged to pray all five hours (not literally 60 minutes, but prayer times) daily (if they miss one, they must confess it!), but priests are not obliged to say Mass any day other than Sunday.
jilly4ski mentions a handbook of prayers, and so do I

I highly recommend the
Handbook of Prayers (the student edition is perfect); it has all the prayers you need, including basic prayers, novenas, chaplets, rosary meditations, stations of the cross, an incredible examination of conscience, prayers for before and after Mass, points of meditation, and even an instruction on “how to be a better Catholic”. The ISBN is: 978-1-936045-00-6; it is published by MTF. You’ll love it. My Dogmatic Theology professor just this evening in class recommended this book for all the students. It’s great!
God love you
