What I would do. Start here:
http://quizlet.com/subject/compounds/

Now the names can be broken down into their respective parts:

ammonium nitrate = NH₄NO₃
beryllium nitrate = Be(NO₃)₂
iron(III) nitrate = Fe(NO₃)₃
lead(II) nitrate = Pb(NO₃)₂
magnesium nitrate = Mg(NO₃)₂

So if you remember that a nitrate = NO₃, this task becomes a lot easier.
If you learn the periodic table first and combine this knowledge with the compounds, you're almost there.

There are enough posts on this forum about learning the periodic table, so let's skip that and assume you can do that.
How do you remember that nitrate = NO₃? Of course it helps to know (from the periodic table) that N = nitrogen, but your question was how to do this with mnemonics.

First the name. Nitrate sounds like 'night rate'. Visualize for example a movie being played in a cinema at night, and the movie is cheaper because there is a 'night rate'.

Now NO₃. Let's assume you use the Major System for numbers, NO₃ can become mnemonically Not On Monday (m=3).

So the image becomes a movie theater that plays a movie a night. There is a Night Rate, but Not On Mondays.

Great reply Kinma! :) I would have done something along the same line.
