It is not clear from your question what you want to study and in which level. The answer could have been better if you have mentioned in detail about your educational background. So first make it clear.

I want to know about the low tuition fee colleges in Ireland. I want to apply for admission in one of the Irish colleges with low tuition fees. Please guide me.

Visit Dorset College website: http://www.dorset-college.ie. The tuition fee is quite low there that ranges from 3500 to 5800 Euros per year.

Ireland still has Free University Tuition Fees for EU students.
Any UK or EU resident can go to University in Ireland and will not have to pay any tuition fees.

These are not tuition Fees - they are called registration fees or student services and are paid annually. These are the Undergraduate registration fees at the main Irish Universities.

Trinity College Dublin - €2250
University College Dublin €2288
University of Limerick €2250
Cork University €2250
NUIG €2250
