How much do tattoos hurt?

Okay so I'm 16, but gathering information for when I'm of legal age to get a tattoo (18). But I'm a WIMP! I've handled piercings pretty okay... but like I'm not good with too much pain. So how much pain do you think a tattoo is? I know it also depends on where you get it put as well
Here are my designs (these are inspo pics I do want to change them up and personalize them):
I want to do a combination of these two and make them a half sleeve that I can later expand into a full one.
I want this little cutie but without the "CF" on my ankle or behind my ear/under my hairline on my neck.
I want this one on my ankle as it is more personal so I don't want it shown to the world (plus I plan on being a child psychologist, so I don't want them seeing that I have a tattoo as a reminder of the fact that I too was once suicidal). But it basically means it's where I could've ended my life, but I didn't. I really like the splash of colour as well haha I think it's unique.
This one I want on either the nape of my neck like shown or on my wrist, it has a hidden symbol, the "stem" is the symbol for anorexia, which I've so far overcome. And I want reminders of how far I've come and how much I can. The lotus is also a symbol for peace and recovery I'm pretty sure. 
I want this in cursive under my ribs, not big or anything, just a small tattoo. I find this so inspiration and it's helped me when I do have a breakdown and want to starve myself. So since I found that quote it's my go to instead of all that "yay you can do it'll it's more grounding to me
I want to do this as another half sleeve. Because supernatural is my go to when I need to eat. Often when I need to eat I'll sit in front of the television so I don't think about it as much, same with after. It's helped me a lot. There are a lot of changes I wanna make to this one too. I like the car shape and that's my favourite line, but some of the things like the skull and roses don't make sense to me so I'd change them into like cas' handprint + sam's show or angel wings :). 
I want this to finish that half sleeve one, I don't know if I'll transform it into a full sleeve or just do like 3/4 or make the other supernatural one a little smaller and keep it a half sleeve. But I have time to think 😁
My boyfriend and I are getting devil warding symbols for SURE (matching couples tattoos!!) I want mine a bit more like this with colour and am gonna get it like on my chest... 
I do worry a little about my tattoos and the profession I've chosen I want to do, be they're all coverable so they could still work 🤷🏼‍♀️🤷🏼‍♀️
I feel like I've deviated a lot from the question.. anyways, tell me your tattoo stories and how much they hurt
(And this is anonymous because I shared a lot of personal details I don't really want people knowing my name just yet.... )
