Well, apparently your church likes to call them prayers...So why shouldn't I, and you...
So, why the obsession? We know the saints aren't God, and aren't gods, either. But they're closer to God than you are, and if I wouldn't hesitate to ask your prayers, why should I hesitate to ask theirs?
Then why do you ask them for things that only God can provide??? Here's a couple of your prayers...
Powerful Aid Prayer to St. Michael
Glorious Prince of the heavenly hosts and victor over rebellious spirits, be mindful of me who am so weak and sinful and yet so prone to pride and ambition. Lend me, I pray, thy powerful aid in every temptation and difficulty, and above all do not forsake me in my last struggle with the powers of evil.
Amen.

Prayer to St. Francis for Life
Gentle St. Francis, you were so devoted to the humanity of Christ. Your heart burst with appreciation toward O God for taking on human life. You saw beauty and goodness in all living things - in birds that sing, the fish that fill our waters, and all that lives in nature.
Help us to imitate your reverence for life wherever it may be. Especially, humble Francis of Assisi, help us to help others to see the worth of each living, unborn baby sheltered in its mother's womb.
May all people have the grace to understand that these tiny, budding lives have the right to life, liberty, and the pursuit of happiness.

I doubt that you ask one of your frinds to heal you, or provide a wife/husband for you...Why would you ask someone you hope is in heaven to do it???
Nor is such a request in the prayers you posted.
