a- a finished thread with priority of MAX-PRIORITY.
b- a runable thread with priority of 1
c- a runnable thread with priority of 2

Yes.

Q WHICH OF THE FOLLOWING THREADS WILL MOST LIKELY TO RUN FIRST?
a- a finished thread with priority of MAX-PRIORITY.
b- a runable thread with priority of 1
c- a runnable thread with priority of 2
d- suspended thread with priority of 5

If by a finished thread you mean a thread that has completed execution of its run() method then it's, uh, out of the running. A supended thread will not become runnable again unless it is revived with resume(). So you are left with b and c. Whoever runs first is really at the mercy of the thread scheduler, which is implementation-dependent. But since we are talking about likelihood instead of certainties, I'll place my bet on c.

my second question is :-
Q WHICH OF THE FOLLOWING IS NOT A VALID STATE OF THREAD?
a dead
b running
c runnable
d altered

What on earth is altered?

my third question is :-
Q CAN INHERITED SYNCHRONIZED METHOD HAVE ITS MODIFIER CHANGED IN THE SUBCLASS

A method that overrides a synchronized method may or may not be synchronized.
