electromagnetic spectrum is the group of all possible frequencies or wavelengths of electromagnetic radiation
Technically, yes. A laser is a concentrated beam of monochromatic (usually) light. Given that light itself is considered to be part of the electromagnetic spectrum and that that spectrum is referred to as electromagnetic radiation (as it doesn't need a medium to travel through) then one could deduce that a laser beam is radiation. In addition, gamma radiation also forms part of the electromagnetic spectrum.
A spectrum can take many forms. It usually means a range or group of things. For example... White light is split into the spectrum of colours by a prism. Radio waves form a small part of the electro-magnetic spectrum.
"radio" there is no real lower limit (in theory).
A spectrum is a band of seven colors obtained after white light is split. This can be understood by the fact that if a white light (sunlight) is passed through a prism and allowed to fall on a white screen, the seven split colors can be seen. The arrangement of the colors are in the order: violet, indigo, blue, green, yellow, orange and red. This arranged group of colors is called a spectrum. A rainbow is an example of a natural spectrum This also may help you remember the order of the colours in the spectrum- R(red) O(orange) Y(YELLOW) G.(green) B(blue) I(indigo) V(violet) Roy G. Biv\ you can also remember it as: (R)ead (O)ur (Y)ellow (G)rafic (B)ecause (I)t's (V)ictorious
Here the word spectrum denotes the group of waves.

Light is a range of frequencies of electromagnetic radiation. This is the same stuff that makes radio frequencies, X-rays, microwaves (like the ones used to heat food). The range or group of frequencies that make up visible light plus ultraviolet and infrared light are referred to the visual spectrum. The others are the radio spectrum, the microwave spectrum, etc.
