I'd have a symbol

Question

A mutual friend of mine has gone crazy! They sent to my friend questions that don't make sense:

Why is the letter V curvy????

Why is letter O carrying plates on their head?

What?? Why is the number 2 bumpy???

Oh MY GOD! Why is that funny number pointing right?????

Why does the letter N have a earring???

M, why did you do fishing??

Another mutual friend has done that too but with a different approach:

I am gonna circle the multiplication sign.

Why is the female sign a demon???

Oh ok, its back.

As I said, I am gonna also circle the addition sign.

Oh god, I erased the line from Males.

I can't solve this math problem, 21? or 24?

What are they talking about?

Here's a bonus:

Continue the two things that they sent.

Answer 1

The first friend

appears to be describing the zodiac symbols: ♈, ♉, ♊, ♋, ♌, ♍. (The "plates" are the horns of ♉, the "funny number" is 69, and the "fish" is the right side of the symbol.)

Similarly, the second friend

is describing the planetary symbols (starting with the sun): ☉, ☿, ♀, ⊕, ♂, ♃. ("It's back" is referring to the normal 'female' sign, which also represents Venus. The "math problem" is a symbol that looks vaguely like a ligature of either 21 or 24.)
