解析：
(1)
$\begin{aligned}(-3)-\left(+\frac{1}{3}\right)+5-\left(-1\frac{1}{3}\right)&=-3 - \frac{1}{3} + 5 + 1\frac{1}{3}\\&=(-3 + 5) + \left(-\frac{1}{3} + 1\frac{1}{3}\right)\\&=2 + 1\\&=3\end{aligned}$
(2)
$\begin{aligned}(-12)-5+(-14)-(-39)&=-12 - 5 - 14 + 39\\&=(-12 - 5 - 14) + 39\\&=-31 + 39\\&=8\end{aligned}$
(3)
$\begin{aligned}0.25+\left(-\frac{1}{8}\right)-\frac{3}{4}-\left|-\frac{7}{8}\right|&=\frac{1}{4} - \frac{1}{8} - \frac{3}{4} - \frac{7}{8}\\&=\left(\frac{1}{4} - \frac{3}{4}\right) + \left(-\frac{1}{8} - \frac{7}{8}\right)\\&=-\frac{1}{2} - 1\\&=-\frac{3}{2}\\&=-1.5\end{aligned}$
(4)
$\begin{aligned}\frac{5}{6}+\left(-2\frac{1}{2}\right)-\left(-1\frac{1}{6}\right)-(+0.5)&=\frac{5}{6} - 2\frac{1}{2} + 1\frac{1}{6} - \frac{1}{2}\\&=\left(\frac{5}{6} + 1\frac{1}{6}\right) + \left(-2\frac{1}{2} - \frac{1}{2}\right)\\&=2 - 3\\&=-1\end{aligned}$
(5)
$\begin{aligned}5\frac{3}{4}-\left(-4\frac{2}{3}\right)-5.75+\left(-7\frac{2}{3}\right)&=5.75 + 4\frac{2}{3} - 5.75 - 7\frac{2}{3}\\&=(5.75 - 5.75) + \left(4\frac{2}{3} - 7\frac{2}{3}\right)\\&=0 - 3\\&=-3\end{aligned}$
