Sharing (characters) is Caring!

Question

Overview

Consider the following task:

Given a positive integer n > 0, output its integer square root. The integer square root of a number n is the largest value of x where x² ≤ n, usually expressed with the formula floor(sqrt(n)).

Examples: 25 -> 5, 24 -> 4, 40 -> 6, 1 -> 1.

This task is easy enough on its own. However, in this challenge, your task is to solve this in as many languages as possible using a set of only 25 characters.

Example

First, you need to pick a set (no duplicates) of 25 bytes. It may look something like this (note the leading space):

 ()*-.05:=>Mabdhilmnqrst|

Your challenge is then to, using only characters in this set, construct a solution to the problem in as many text based (sorry, Piet) languages as possible. You can use characters as many times as necessary, but you must not use characters outside the set.

The solutions can be either full programs or functions, but not snippets. For example, using this set of characters, I could do:

M -> (int) Math.sqrt(M)    // Java (lambda expression)
M => Math.sqrt(M)|0        // Javascript (unnamed function)
lambda M: int(M**.5)       // Python (lambda function)

As I've used 3 languages, this would give me a score of 3.

Please also include the set of bytes you are using in your answer.

Rules

This is a rosetta-stone challenge - your score is the number of languages your submission includes. The highest score wins. Standard loopholes apply.
For this challenge, a 'language' counts as a distinctly different programming language - multiple versions of the same language (Python 2, Python 3, etc) are banned.
Programs only need to work for inputs within the language's standard integer range.
Programs with the exact same source code (polyglots) are not allowed.
To be more specific, it is a set of bytes, not characters - so you can use the 05AB1E £ and the Jelly ɱ as the same character (because they have the same codepoint).

Please don't feel as though you have to beat all other solutions - if you have an interesting answer, post it!

Can our solution be in Piet if we have the code be the raw ppm? (e.g. P3 10 10 255 ...) — Wheat Wizard, Commented Jan 10, 2017 at 2:58
We need another pixel based language so we can have polyglots with poor old piet — MercyBeaucou, Commented Jan 10, 2017 at 3:37
Can we count a polyglot of A and B as language A if we provide another solution that only works in B? — Wheat Wizard, Commented Jan 10, 2017 at 5:25
Could you clarify "distinctly different"? For example, is Numberwang--using digits instead of []<>.,+--- distinctly different from Brainfuck? What about SNUSP, a 2D Brainfuck derivative? For both of them, the resulting code would not work in Brainfuck. — JungHwan Min, Commented Jan 10, 2017 at 6:06
@WheatWizard you can't have two programs that are exactly the same, but if you modify one to be different then it's allowed. And yes, if you really must, you can use the raw ppm as "text" for Piet :P — FlipTack, Commented Jan 10, 2017 at 7:25

\$\begingroup\$ @ConorO'Brien Although it's shorter, it would mean to add c to the list of characters. He's already using both m (in the Oasis sub-answer) and f (in the Japt and Pyke sub-answers). \$\endgroup\$

I'm trying not to use any alphabet characters...

Brainfuck, Brainfuck++, Brainfuck-ng, Braintrust, ...

Doesn't work for over 224 because 256 (= (sqrt(225)+1)^2) overflows.

Replaced all -s with +s to use one less character. (e.g. - -> 255 +s)

Original Program

Per meta consensus, this code should be okay, even though no interpreters are currently available.

Using ()*/12 dlinpqrstu and newline (18 characters) so far.

Common Lisp

isqrt

A built-in function.

QBasic

input q
print int(sqr(q))

Python 3

print(int(int(input())**(1/2)))

Python 3 used for floating-point division without decimal points.

Pip

q**/2//1

Unnecessarily golfy to show off the unary inversion operator /. Takes input from stdin. Try it online!

tinylisp

(d sqrt (q((n nsqr input) (i (l input nsqr) (s n 1) (sqrt (s n (s 1 2)) (s 2 (s (s (s 1 n) n) nsqr)) input)))))
(q((input)(sqrt 1 1 input)))

sqrt is a helper function whose arguments are: the current guess n, n squared, and the input number. If input is less than nsqr, we've gone too far, so return n minus 1; otherwise, recurse, adding 1 to n and adding n + n + 1 to nsqr. (The math is a bit complicated because tinylisp only has subtraction built in.) The second line defines our actual function, which takes a single input and returns the result of sqrt with n starting at 1.

If you would like to add {}[] you can add Brain-Flak. Here's the program — Wheat Wizard, Commented Jan 10, 2017 at 2:51
