Those look pretty good! close-up photography is an acquired skill..you will get better at it! I think you are off to a great start!
P = Program mode..camera makes all the exposure settings for you, with whatever it "thinks" is best.
Tv = Shutter Priority mode..you pick the shutter speed you want, and the camera automatically gives you the correct aperture setting (f-stop) to make a properly exposed image..
Av = Aperture priority mode. you pick the f-stop you want, and the camera automatically gives you the correct shutter speed to make a properly exposed image..
M = Full manual..you pick everything..the camera will tell you if the exposure is good, via the light meter, but it wont stop you if you are going to over or under expose..the camera makes no decisions on its own in full manual mode, you do it all.
Dont know what the C1 and C2 are..havent heard of those..what is the make and model of the camera?
any of those settings *can* be used with any lens..the setting you choose has more to do with what effect you are going for, and what is most important..
For sports photography for example, you might want to take advantage of Tv - Shutter Priority mode.
you pick the shutter speed..a fast shutter speed like 1/500 or 1/1000 of a second (assuming the light will allow it) and then let the camera pick the f-stop for you..you want to choose the shutter speed, because you want every shot to "freeze" the action..
For close-up/marco photos, I would start out playing with the Av - Aperture priority mode..you pick the f-stop, which controls depth of field, and the camera will automatically give you a shutter speed..play with small and large f-stops (apaerture openings) and watch how the depth of field changes..small f-stop gives you bigger depth of field (more is in focus front to back)..larger f-stop give you less depth of field, less in focus..you usually wont be able to do the full range, because of the lighting..the camera will tell you if you are going to be properly exposed or not..
that should be enough to chew on for now!
any other questions, just ask..
