Good thermostat

By different size do you mean different length or different width? Its dependent on their wattage. Yes it could easily handle 5 UTHs but there is going to be a temp difference if they are not the same wattage.

I have three medium Pad's , one large pad and one small pad.

You need a seperate thermostat for each heating element (unless you it has dual features like the Herpstat 2 which can control two heating elements)

i jsut wanna be able to control the lamp... so it doesnt get to hot

From what I understand, it's not the number of elements but the wattage that matters. Many thermostats come with multi-plugs to plug in different heat sources. The Herpstat 2 is essentially two thermostats and you can plug in multiple heat sources in each one as long as you don't go over the rated wattage.

However, 5 UTHs is a lot and would probably go over the rated wattage for Helix and Herpstat, although a Ranco or Johnson could probably handle the load.

I think the problem here is that he has 2 DIFFERENT kinds of heating elements. You can't mix and match wattage otherwise you won't get a consistent temp. As long as you dont exceed the max of the unit you can put as many elements as you want. I have 10 on one unit without issue. 3" is 10 watts per foot, 4" is 8 watts per foot and 11" is 20 watts per foot I believe.
