Anyhow, I can only answer few. I'm not sure with some.
m is a secant line
n is a tangent line
angle 1 is a central angle
angle 2 is an inscribed angle /not that sure
angle 3 is an angle formed by secant and tangent lines
C is the center of the circle
A is a point on the circle /not sure
Segment AB is a diameter
Segment BC is a radius
Segment BD is a chord
E is the intersection of tangent and secant lines /don't know if there's a term for that
angle B is an angle in a semicircle (it is 90 degrees)
D is point of tangency
Segment AC is radius
angle 4 is an inscribed angle /not that sure though

Answer 11

@jim_thompson5910 can you check my answers??
1. secant
2.tangent
3.central angle
4.inscribed angle
5.angle formed by a secant and a tangent
6.central angle
7.tangent
8.diameter
9.radius
10.secant
11.point of tangency
12.inscribed angle
13.tangent
14.radius
15.inscribed angle

Answer 12

for #6, C is a point, not an angle

Answer 13

# 7 is incorrect

Answer 14

# 10 is incorrect

Answer 15

# 11 is incorrect

Answer 16

# 13 would be the point of tangency

Answer 17

@jim_thompson5910 this is my last question

is 4 inscribed angle?
is 7 point on the circle?
is 11 intersection of tangent and secant lines?
is 12 angle in a semicircle?
is 15 inscribed angle?

Answer 18

is 4 inscribed angle? yes

Answer 19

for #7, that's all we can say really, so yes

I guess you could also say that point A is one point of the intersection of the secant line and the circle

Answer 20

is 11 intersection of tangent and secant lines? yes

Answer 21

you already did 12 and your original answer is correct

Answer 22

same with #15, your original answer for that is correct
