I'd mark these as being okay:

(b) I'll be playing tennis at this time tomorrow.

(d) I'll be playing tennis at this time of day tomorrow

(f) I'll be playing tennis around this time tomorrow

(h) I'll be playing tennis about this time tomorrow.

Thanks in advance.

(a) is OK, too.

Thanks for the help, johnnyG and joadbres.

I'd say a,b, f and h are OK. a and b sound more formal. h is less formal. To be even less formal (though not strictly correct), you could say "I'll be playing tennis this time tomorrow".
