First of all, the EITHER statement is restricted to 2 possible conditions: Either <arg> OR <arg2> otherwise. A string of ORs and IFs is not allowed.
You need to use the CONDITIONAL statement which can handle a large number (255?) possible conditions to assign the resultant value. I could not decipher your logic in your example but a CONDITIONAL statement to do what you want might look something like this:
CONDITIONAL {
(($n2_PROMPT_USER - $n3_PROMPT_USER) GT 0.00003) 180.0,
(($n2_PROMPT_USER - $n3_PROMPT_USER) LT 0.0002) 150.0,
(($n2_PROMPT_USER - $n3_PROMPT_USER) LT 0.00075) 200.0,
.... (fill in the rest of the conditions)
(default) -999.0}
Please realize two things when using the CONDITIONAL statement --
1. The modeler will parse line feeds and spaces without difficulty. Therefore structure your statement so you can more easily debug it; and,
2. The first condition that is TRUE will produce the output value. Therefore always put the default condition (always TRUE) at the end and assign the background value.

2 possible reasons:
If (default) is not producing the value -999 then some other condition must be TRUE before reaching the default statement.
or
Your output file is not a floating point file. In order to record a negative number the output file type must be floating point or a signed 8- or 16-bit. Signed 8-bit will only record up to -127 so your output file must either be floating or signed 16 bit.
From your previous post wanting to assign colors (which can be done in the modeler language, not in the graphic modeler) it is apparent that you want these data to be Thematic in nature. By definition thematic data must be unsigned integer values which will preclude the use of -999 as a background. Use 0 (zero) as a default and life will be easier.

Not sure what your questions are.
To use a .img in ArcGIS no conversion is necessary. ArcGIS GRID format is a floating point raster, not as flexible as .img format.
Don't know what you mean by land masking.
