Are there any other shorter expressions for 8 by manipulating exactly 4 4?
$begingroup$
The label $4times 4 -4 -4$ for 8 seems to be too long. I am looking for other shorter ones while maintaining the constraint of only using four 4.
Are there such expressions?
integer-partitions

What about $(4+4)cdotfrac{4}{4}$? :-D

Here is one: $frac{4times4}4+4=8$
Here is another one: $frac{4!}{4-frac44}=8$
$endgroup$
$begingroup$
I accept this answer because the second is relatively short.

The first one probably looks more consistent with the others if written as $4 times frac{4+4}{4}$.

We have $8=4+4^{4/4}$, which plays nicely with your existing $4=4+4^{4-4}$.
Edit: Or $8=4+log_4 4^4=log_4 4^{4+4}$, if you want to bring in a new ingredient.
