First we need to know :

A rational number is a number that can be express as the ratio of two integers. ... However, one third can be express as 1 divided by 3, and since 1 and 3 are both integers, one third is a rational number. Likewise, any integer can be expressed as the ratio of two integers, thus all integers are rational.

So according to your question :

$\sqrt{24} \\ \\ = \sqrt{2 \times 2 \times 2 \times 3} \\ \\ = 2 \sqrt{2 \times 3} \\ \\ = 2 \sqrt{6} \\ \\ this \: number \: do \: not \: fulfill \: the \: condition \\ of \: rational \: number$

______________________〽

$\frac{ \sqrt{2} }{7} \\ \\ this \: number \: is \: in \: the \: \frac{p}{q} \: form \: so \: it \\ \\ is \: the \: rational \: number$

______________________〽

$\frac{ \sqrt{25} }{5} \\ \\ = \frac{ \sqrt{5 \times 5} }{5} \\ \\ = \frac{5}{5} \\ \\ = 1 \\ \\ this \: number \: do \: not \: fulfill \: the \: condition \\ of \: rational \: number$

______________________〽

$\sqrt{7} \\ \\ this \: number \: do \: not \: fulfill \: the \: condition \\ of \: rational \: number$

Thnku!
