How do you graph a step function

Graphing calculator can graph step functions. You need to learn the syntax of the command for the different calculators. As to showing an open point, I am not sure it pertinent. The resolution is limited and the calculator has to use finite increments to draw points. The last drawn pixel may be as close to your open point as possible but you should not see the open point (it is skipped, isn't it?

How do you find the derivative without values for x

I am not sure I understand what you want, but if I am guessing right, you need to calculate formulas for derivatives, where the name of some variable appears eg= d(x^2)/dx = 2 x.
Sorry, the calculator does not have a CAS, you cannot perform symbolic calculations regardless of the subject (derivatives, integrals, sums of series, factoring polynomials, expanding polynomial products, polynomial division, etc.)

I don't know what all the buttons mean ??????????????????

You cannot be serious. The digit keys allow you to enter the digits that make up the number you are using in your calculations. +, x, - / allow you to perform an addition, a multiplication, a subtraction, or a division. Keys with x^2, sin, tan, cos, log, allow you to calculate the relevant functions.
You get the idea.
To learn how to use the calculator, read the manual. At least skim through it looking for instructions on how to use a particular task. There is no shortcut.

How to get mod on it

If you are thinkink of the modulo function, usually shortened to mod(, I am sorry to say it but that function does not exist on the calculator.
However, there is MODE button that one uses to set the operation mode of the calculator.
You have three principal mode setting
COMP: the general computational mode
SD: a statistics mode to calculate Standard Deviations
REG: to perform REGression analyses on statitical data.

Once you have chosen the preferred calculator mode (COMP, SD, or REG) other choices (dependent on the main calculator mode) will be available.

Im trying to make a piecewise function with more than 10 functions what can i do???

You can actually represent all pieces of the function as a single function. There is an exemple in the calculator manual at page 17-4. You can use it to learn how to implement your function.
The relational operators (less than or equal to, etc.) are accessed through the TEST menu.
hope it helps.
