The equal sign in Excel is used to start a formula. All formulas begin with the equals sign. It can also be used for comparing things. In the following example, the first equals sign is starting the formula and the second one is comparing cell A2 and B2:
=A2=B2
The equal sign with the slash means "is not equal to".
"At least" is expressed with the "greater or equal" sign, for example, x >= 100. (I don't know how to draw the greater-or-equal sign here - it is a horizontal line beneath the greater sign).
The greater than or equal to sign is "≥".
The less-than sign alone means "less than"; if there is a line below, it means "less than or equal".
An inequality must have a greater than sign (>) OR a less than sign (<) OR a greater than or equal to sign (≥) OR a less than or equal to sign (≤).
If you mean in Excel, yes: you must always start a formula with an equal sign.
The combined sign has no special meaning. Any formula in Excel starts with an equal sign. To refer to a cell, you can write, for example, =A1. This can also be written as =+A1. The "+" isn't really necessary in this case. Most likely, a user started the formula with a "+" (out of old habit, since that's what people used to do in older spreadsheet programs), and Excel added the equal sign, which is required in Excel, automatically.
An equal sign because in order for the formula to go through correctly it has to have an (=)

The equal sign with the slash means "is not equal to".
By 'an equal sign with a lightning bolt [through it]', do you mean '≠'? That means 'not equal to'. For example, 6≠9.
Not in Excel.
Every formula, equation, or function starts with a equal sign in a given cell.
Yes, in Excel, every formula must start with an equal sign (=) to indicate to the program that it is a formula and not a regular text entry. This is a key rule in Excel syntax that helps differentiate between data and calculations. Omitting the equal sign will result in Excel treating the entry as text rather than a formula.
It means the figures on either side of the equal sign have equal values to each other.
