RAM is used to store captured data. You define condition which will be used as a trigger for internal data capturing in real-time. After that you can download this data from FPGA through JTAG to analyse in PC. CPLD has no memory (just limited number of FFs), so there is no place to store captured data.

In fact the chipscope only makes state analysis!
When you are using the CLK signal for trigger/clock you can't see it!
You must have an additional signal with higher frequency (for example x2 or more) and this signal is use for the chipscope trigger/clock, now u can see your CLK signal.
For this you can (...)

Just add reset signal, and give trigger on that, then press reset button, if in this case also same problem comes then your clock is not running. Make some counter which runs on clock (used by chipscopro) and assign 27th bit to led available on your board and varify.

1) What is the maximum speed at which we can watch Flip-flop value changing through chipscope ?
I'd say it is directly proportional to your flipflop clock. If you use 300MHz clock, you can watch flipflop value changing at 300MHz rate. No doubt.
But remember, that this is true only for synchronous designs.

What process? are you trying to halt the FPGA? you cannot do that unless you design it in such a way.
I dont know why you dont want to use triggers. All chipscope is is a monitor - you need triggers to force a download from the continuous buffer on the FPGA to the PC.

RB0 is a TTL input when used as a general purpose IO. Thus, the levels are 0.8V max for LO. 2.0V min for HI.
When you configure it as an interrupt input, it becomes a Schmitt trigger input. That is, it has two definite thresholds at which the actual output switching occurs, with a fairly large hysteresis. A Schmitt trigger input buffer switches
