there are contradictions on these terms, coz a boot code may or may not be a startup code but startup code maybe perform task that is done be a bootcode.

startup code is executed first when you power on your controller or a processor, job is this code is to prepare your hardware for booting or to run the boot code so its the basic code that runs when you power up your controller/processor. this is minimum code that is required for a controller to run properly.

boot code runs after the startup code finishes, your boot code executes and initialize your hardware for your application code to run. boot code maybe big or small depending on your application.

EMULATOR:
Emulation refers to the ability of a computer program or electronic device to imitate another program or device. A hardware emulator is an emulator which takes the form of a hardware device. Examples include the DOS-compatible card installed in some old-world Macintoshes like Centris 610 or Performa 630 that allowed them to run PC programs and FPGA-based hardware emulators.
emulators also come with FPGA and DSP kits

read this link for example on emulators
http://stason.org/TULARC/pc/apple2/emulator/1-1-What-is-an-emulator.html

simulator:
A computer simulator is a program run on a computer for the purpose of simulating some sort of system, in order to get a better idea how the system functions. A computer simulator may also be used to simulate another computer. There are two main types: the full-system simulator and the Instruction Set Simulator (ISS). This type of computer simulator is often used to test new software on a wide range of hardware configurations, without actually having to use the physical computers.
just like a Proteus that is a simulator that run program and clear our expecting idea

DEBUGGER:
A special program used to find errors (bugs) in other programs. A debugger allows a programmer to stop a program at any point and examine and change the values of variables.
visual studio,keil and almost every language software has a debugger integrated into it
